RE: Keeping fridge cool in high 90s temps
Few questions...
*are the INTERNAL Fans operating (1/freezer & 1/food compartment)
DC power from P4 2 pin connector (pin 1) far bottom right on circuit board
*are the EXTERNAL FANS running (P1 10 pin connector -- pin 5) DC goes to t-stat then to the Fans
Suggestion:
Unplug thermistor leads (temp sensor on 2nd fin in food comaprtment) and let fridge run W/O temp control (set tp MAX temp setting ---then if food comaprtment gets to cold you can lower the temp setting ----operates on Backup Operating Suystem which is 'timed base' vs temp based

RE: Atwood Water Heater Question
Since 2004 Atwood combo WHs use common DC to control both electric & propane heating functions
Running out of water in fresh water tank would NOT empty the WH Tank....
Common DC from a FUSED source goes to Both On/OFF switches then to the common circuit board
Did the RED Fault Light come on?
*Check the DC Dist Panel Fuse that supplies WH with DC...
*Check the 2A DC fuse ON the WH Circuit Board
*Check the 'thermal fuse' (in the clear tubing) that is connected to T-stat via Brwon Wire (Remove from circuit abd plug brown wire directly onto T-stat to test if WH will come on (One shot thermal fuse)
Those items are common and would prevent either heat source from functioning
Use a Voltmeter to follow the DC...........

No 'resets' on WH except for Fault Light/Lock out (turn On/Off switch OFF---wait 30 sec---turn ON)

RE: DC operation of fridge
YES it is OK yo use propane while traveling...........one caution isto turn fridge OFF when fueling
As for camper battery NOT charging from truck...
Does your camper use a 4, 6 or 7 pin umbilical cord to plug into truck
Have to have a 'charge line' from truck to camper
Also check truck fuse box and see if a fuse/relay has to be installed for truck sytsem to charge camper battery

RE: Norcold n7v not running lp
Norcold Polar 7 Series
IF by 'fault code 2' you mean
RED Flashes 2 times then off for 5 seconds then repeats that is indicating an Internal Fault (circuit board bad)
See pg 17 thru 25
17 lists all faults

RE: Laws/Regulations for RV Fresh & Waste Water Service
In a home the bathroom sink and toilet share same room, same cold water plumbing.
One just has to remember to not wash hands in toilet or pee in sink
Same for an RV.....
Pay attention and don't cross contaminate or use same hose for potable and waste.

RE: Electricity? Never touch the stuff
Kinda hard for an 'electrician' to screw up a 50A RV install
Now 30A..........
Need to watch them like a hawk cause that can be 120V OR 240V

RE: fridge code. refrigerator
Check converter AC circuit breaker. Use voltmeter to measure converter output voltage. Check two reverse polarity 30/40 amp fuses on converter. Check water level in battery's. Have batteries load tested.
THIS^^^^^
YOur converter is failing and battery is low cause converter is not maintaining/charging battery

RE: gas line interferes with drain plug
Having operated 'boilers' of every size/design for over 30 yrs the one thing I do know is about the SAFE operation of them.
Water heaters are just small boilers
Every component attached to boiler MUST meet the temp/press rating of boiler in order to be SAFE.
AND the smaller the hole the more restrictive is becomes when draining/flushing
Just saying....
Pretty sure a brass cockvalve is going to be safe when compared to a plastic plug.
Convenience of the cockvalve trumps the plastic plug for part timers.
Drain plug is NOT plastic
It is NYLON and rated for 300*F PLUS/180 psi

RE: Model of WH in 1998 Southwind?
Thanks, that is the info I need. MH is being parted out and I wanted to know if its WH would fit in another RV that needs a replacement WH.
(Haven't talked to the owner of the Southwind yet)
See info in your other post about Atwood Water Heater

RE: Atwood Water Heater Tank Crack Repair ? UPDATE
Cut out openings
6 gallon
12 1/2"H X 16"W X 19 1/2"D
10 gallon
15 1/2"H X 16"W X 20 3/4"D
6 for 6 and 10 for 10
Her newer version can be replaced by the earlier version
AC side needs 120V AC to on/off switch then to separate set of T-stat/ECO on backside of water heater tank then to element
OEM ON/OFF is also back there
DC side for propane....12VDC to On/Off switch then to thermal fuse to t-stat (then OEM wiring to control board to eco to gas valve)

RE: Model of WH in 1998 Southwind?
Couple of pics I looked at on line for 1998 Fleetwood Southwind show exterior panel for an Atwood WH
Model....
COuld be just gas (G6A-7)
Could be a combo with pilot flame (GC6A-7P)
Could be a combo with electronic ignition (GC6A-7E)
Could be combo with motor aid....GCH6A-7E
Could be 10 gal units.....GC10A-3E
Or with motoraid GCH10A-3E
That vintage the electric/propane are completely separate functions/controls

RE: gas line interferes with drain plug
I took my plug out completely and installed a 90 degree drain valve with a hose that is routed under the RV to drain.
Hope that hose is temp/pressure rated for above 210*F/150 psi
Temp/press that COULD be reached/exceeded should t-stats fail to shut down heating source
Drain hole is small to begin with (1/2")
Valve cuts that size down even more so effective draining of crud is hampered.
A little bit of overthinking here.
Why would a drain hose that’s about 12” long need to be temp/ pressure rated.
Or are you thinking of the Temp. Relief Valve.
I don’t full time in my RV so the “crud” buildup would be minimal to non existent and I drain my tank after every trip.
It’s a modification that I wanted to do to my RV. If you don’t agree with it, then fine, move on to the next post but quit trying to impress everyone with what you think you might know.
Having operated 'boilers' of every size/design for over 30 yrs the one thing I do know is about the SAFE operation of them.

RE: Propane vs AC on Dometic Refrigerator
YES, will run cheaper (If you paying for electric)and get colder than AC. Move the thermister down on the fins when on Gas.
Why do you want OP to move thermistor?
Thermostat controls heat cycles regardless of heat source based on feedback from thermistor.
On fridge WITH temp settings on upper panel.thermostat is calibrated for temp sensing from thermistor on a specific FIN position
On fridges with "AUTO TEMP CONTROL" (NO temp set points)
Moving it DOWN means warmer
Moving it UP means Cooler
Overall temp effect is 4-6*F
Propane & electric transfer basically same temp to boiler section
Propane does 'start' the process sooner due to hot flame

RE: gas line interferes with drain plug
Yes the drain plug is right behind the gas line/gas valve
A socket can not be used unless you remove gas valve
Use a combination open/box end wrench over the top of gas valve
7/8" or 15/16" depending on plug vendor
Loosen with wrench then remove with fingers
Install finger tight then snug up with wrench

RE: Propane delivery noise
Dometic IS Atwood.....
There is NO adjustment of Gas flow or air flow...both are fixed
Orifice/LP System pressure determine gas flow
Venturi affect of gas flow determines air flow.
Loud Roaring Flame suggests damaged burner or high system pressure
