Onan 2800 fuel pump location

Can someone tell me if the fuel pump for the Onan generator is located within the generator case or if it is located elsewhere. And if " elsewhere " where? 2000 Roadtrek Versatile 200 on the Chevy 3500 chassis.

RE: Dometic fridge woes.

Doug - my RV is a 2000. Assume the fridge is the same.

RE: Dometic fridge woes.

earnie1 -- I got the jet from RV Superstore in Vandalia, Il. phone 618 283 4396 handwritten note on the package says DOM#0169353-002... I'm going to call anc check if they have others available. Good luck with yours.

RE: Dometic fridge woes.

UPDATE --- back from trip . new jet was in the mail-- did NOT fit--- not really surprised -- with a selection of brass fittings was able to adapt the fridge to use the new jet. I was replacing a #43 jet with a #48 -- would have preferred maybe a #46 but you take what you can get. THE BEST PART-- fridge is cooling on propane like a champ !! Been a 3 day test with outside temps in the 90s and temps inside the RV sometimes up to 105 degrees. Parked in the sun with fridge side to the sun. The thermostat has been on " 4" for the entire test. Highest temp measured in the food section has been 37 degrees. So no other changes except the jet replaced with a larger one. The #43 was listed in the Dometic manual as the part# for this model. It had been inspected with magnifying glass and endoscope. Cleaned numerous times. Anyway, the thing is working well and I'm happy.

RE: Dometic fridge woes.

trailrider...I just sold my complete set of 120 Holly jets. Unlike Holly, Dometic jets are not real common. Some of the jets for dometic are priced at $50 and more. most are listed for a model # or a part # .. the one I ordered is the only one I found that listed a size..not sure it will even fit... so yes - good idea..execution gets more complicated.

RE: Dometic fridge woes.

ERNIE1 - found the jet on ebay..no guarantee that it will fit picture looks like it but who knows. $10 and I'll take the chance..no more ideas.. no idea how to find it again..I googled "ebay dometic jet" passed the phone and told wife to order. I'll try to remember to let you know if i can get the sellers info.especially if this fiasco works.

RE: Dometic fridge woes.

actually.i have a hopefully bigger jet on order. presently the installed jet is a 43. I have a 48 on order. It will be a while. Jet is supposed to arrive next week but we'll be on a trip..sadly- the manual for this model specifys a 43 jet..you'd think that would indicate that something was amiss with this jet. as we're warned not to poke into it..hard to imagibe one could screw it up cause less flow. UPDATE..I now have a bbq tank and the original regulator rigged up to now bypass EVERYTHING except the burner assembly with the 43 jet..guess what ! same results. Thanks for all the input/ideas. I'll post results when 48 gets tested.

RE: Dometic fridge woes.

Doug... we can eliminate the t'stat as a problem. ( As you suggested earlier) I bypassed all the controls on the LP side. Ran a tube from the unit cutoff valve directly to the burner assembly. Now only things involved are the LP tank, regulator, cutoff valve and Orifice. I had a manometer connected at the test port. 11 inch water column. Manually lit the flame. This arrangement should allow the burner to operate at full capacity with out any complications. refer temp had been maintained at 20* to 22* on electric for at least 12 hours. When switched to gas the refer temp went from 20* to 35* in 6 hours. Those temps don't sound bad but I know from earlier camping trips that the temp would got to 45 of 50 degrees if continuing on LP. I increased the LP pressure from 11 to 13 and then to 15 with no change in flame appearance. Nor did the increased pressures raise the boiler temperatures. Someone earlier had suggested that even though the pressure is correct that the flow might not be sufficient. I don't know how to test the flow but at this point I have to assume that the orifice is not big enough to allow a larger flame but a larger flame is needed to produce more heat. It is ironic that with all this heat I'm wanting more heat to cool my refer.

RE: Dometic fridge woes.

I guess so far all I have found is that the thing works well on a/c. The whole idea of buying the Roadtrek was to be able to boondock at race tracks for 3 or 4 days without running a gen. So I am particularly interested in the LP option. At 5 PM I switched to LP mode. Nothing else was changed. Except the temp inside the rv has dropped from 105 degrees to 94. Within 5 minutes the refer temp increased to 27. The condenser tube I had been monitoring for temp dropped from 114 to 107. I was running a small fan on the condenser fins but turned it off when switching to gas. Without the fan the condenser tube was over 130 degrees at times. Time will tell.

RE: Dometic fridge woes.

I'm thinkin the refer is good. Was worried about a damaged cooling unit. At 8 this AM I moved the selector from MAX to 7 .. the temp has stayed at 26 or below with inside RV temps as high as 101. RV parked in full sun with back of fridge to the sun. Been measuring the the temp of the tube above the evaporator. Some advertisement for a product to protect from overheating says fans on this tube should start at 139 degrees and shut off at 109. Mine has done on its own without fans but I can lower the temp with a small fan. I've tried all kinds of fans, locations and baffles... nothing seemed to help the This tube never got very hot on gas. Gonna let the thing run until this evening and switch it back to LP with no other changes and let it run for 24 hrs. Maybe now that it is hot the LP mode can keep it hot. Earlier while messing with all this the refer was empty. Sometime yesterday I put 2 gallons of water (room temp)in. That was there through the night and was not frozen this AM even though the box temp was 23. Around 8 this AM i opened the box and added 2 frozen blue packs and 5 small palm sized cold packs. The temp went to 25 but was back down to 23 shortly. . have maintained temps within 3 degrees while interior RV temps have increased almost 30 degrees. Been interesting --- will report tomorrow.

RE: Dometic fridge woes.

Doug--- yesterday and last night were cooler than it has been laterly... The fridge ran on A/C since 2 pm yesterday until now. the temp inside the fridge (not freezer) is 23 degrees. The temp selector is set to MAX that bypasses temperature controls and the fridge runs full tilt - always on. Temps inside the RV yesterday was average maybe 85 degrees This AM it is 73 so far. on the LP side -- I should be able to get the fridge to lower the flame by setting the t'stat to OFF. That is supposed to keep the flame at a pilot light size. Then the MAX setting is supposed to keep the flame at full height full time bypassing any temp controls. Todays 23 degree temp was on A/C at MAX setting. I have observed the flame while the setting was on OFF and had someone then switch the setting to MAX ... no difference in the appearance of the flame. I have read that once can hear the difference in the flame sizes. I cannot hear this flame at all. I can hear the flame in my other RV without removing the vent. I guess a smaller fridge might need a smaller flame. I have read that extended use in the MAX setting can cause damage to the cooling unit by overheating it. If this has been damaged could the thing produce the 23 degrees I getting on electric? Or would it just taker longer and not be able to maintain the cold? I guess that "I have read..." quite a bit. Guess I just have not yet read that little gem of info that I need.

RE: Dometic fridge woes.

Tom M ..actually I did check the filter - it looked brand NEW - because it IS. I looked at before I installed the NEW t'stat. It is located in the inlet of the t'stat. I also looked at the filter in the removed t'stat... didn't look much different from the new. EARNIE1 ... the filter is just a small wad of what looks like cotton (maybe a little larger than a pencil eraser) pushed into the inlet of the t'stat. On this particular fridge the controls and most of the LP plumbing is located on top of the fridge and the fridge sits in a compartment that allows no access to them. The only things accessible from the outside vent is the primary shutoff valve and the burner tube ( along with the orifice, igniter, and thermocouple). This fridge has to be disconnected from the LP supply, unscrewed, then slid foreward into the RV in order to access the filter or most anything else.

RE: Dometic fridge woes.

with the temps here in Missouri - I'm putting this problem on the back burner. We have a trip (different camper) coming up soon. When the weather cools, I'm planning to remove the fridge and systematically disassemble each piece of the LP plumbing and blow out in reverse direction of flow. Then I am totally out of ideas. The ROADTREK might be available for sale by September. Thanks to all for suggestions and info.

RE: Dometic fridge woes.

Doug. Yes I remove the baffle each time I swabbed the flue. Looks good - no rust - in tact, no burnt or missing corners, . Had several RVs, this is the best looking one I've seen. Probably because it havsen't been really hot.
btcruzer 07/12/20 02:45pm Tech Issues
RE: Dometic fridge woes.

enblethen Yes, I agree that proper pressure does not guarantee sufficient flow. And it seems that I have insufficient flow (volume). The thermostats method of controlling temp is to allow more flow when cooling is required. That is done by opening up a second passage (sort of a passing lane). If, indeed, the 'stat is opening that second passage then there must be a restriction (unauthorized) somewhere between the regulator and the orifice. I bought the RV used and don't know if the fridge EVER really worked well on LP. It does well on A/C. lunch time --- later
btcruzer 07/12/20 01:38pm Tech Issues
RE: Dometic fridge woes.

Doug The burner assembly has been removed and cleaned several times. The jet ( orifice ) (#43 per Dometic) has been removed soaked, cleaned and blown dry several times. The flue has been swabbed full length several times.

RE: Dometic fridge woes.

Dougranier -- the LP pressure was measured at the port next to the orafice - 11 inch WC per the manual. same pressure at any setting of the thermostat. Didn't examine the filter on the new thermostat prior to installation. Hard to imagine it could become plugged at initial use. Also the same problem with two thermostat -- odds seem high. I guess I did a version of your water temp test. I connected a small test light to the power leads of the heater element. Switched to electric mode and observed for several hours. the light would cycle on/of indicating to me that the thermostat was doing what it is supposed to do - control the temp. The fridge did cool and maintain a stable temp. The same movable piece in the thermostat that controls the electric switch also moves the plunger that controls the gas flow at the same time. I cannot verify that the larger gas passage in the thermostat is actually opening. I can only assume a NEW thermostat is properly adjusted for its intended use. I'm thinking that there must be a restriction somewhere. but the lines and passages are so tiny it is hard to imagine. With the small amount of gas required would a restriction actually lower the LP pressure at the test port? Seems it would have to be after (downstream) the thermostat. The only device other than tubing between the thermostat and orafice is the safety valve that bypasses the thermocouple. That actually looks like a likely place. Unfortunately the fridge is back together and installed. All the controls are on top and hidden until the fridge is disconnected and moved out of the hole.
