RE: Coleman Mach 15 problems......need some help troubleshooting
1. Do you have a 30 amp RV plug at home for the RV?
2. House breaker, I assume your residential house breaker. WHAT AMP is it?
3. Does the fan come ON if you select fan only?
4. IF the fan comes ON, how long before the House breaker trips?
5. The Tstat will NOT be the problem
6. The Upper circuit board will NOT be the problem, unless you remove the cover and see obvious burned wires/circuits.
7. If the fan runs, does the compressor attempt to start or hums?
8. You need this tool to see what the amp reading is when the compressor tries to start.

RE: RM2652 on shore power, but LP igniter still snapping
It’s a 2005 SunLine T-2499
Thanks, just wanted to make sure it was not a 1991 to 1997 model refer. If you start out with the refer OFF and select Auto/120. Does the ignitor start clicking? IF SO, does the gas valve open and the flame lights? IF just clicking, then the rear main control module is suspect. Doug

RE: No gas to stove only
Got the new one installed today and everything is working correctly. Hopefully it lasts for as long as we have the trailer. Thanks for all the responses.
In 44 years and working on thousands of stoves/ranges, I have NEVER had a clogged failed Stove regulator. So, you should have NO worries. Yours was a fluke. Doug

RE: Class A's in Australia are mostly Conversions
Do you know when Tiffin changed at production to RH controls? I have worked at a Tiffin dealer for 44 years and have worked on about 5 in transit from Tiffin Red Bay to the west coast and ALL had LH controls. NONE for the past 5 years, but before 2018. Now, since Tiffin builds the Breeze chassis, they have the capability of choosing RH and LH controls. Tiffin is dropping the Powerglide build at Red Bay. I believe Freightliner is going to start building Powerglides after the end of the year. Doug

RE: RM2652 on shore power, but LP igniter still snapping
I ended up unhooking the igniter so that it no longer sparks. Fridge works fine on 120 V. Gas is off at the gas valve for fridge now. However when I did try on LP, ignitior still sparked when LP was on and lit, fridge cools good on LP.
Stove works fine.
No fault noted. Electric element works perfect. Actually too good. My fridge runs at 27deg and freezer at -4deg. Receptacle has 120v
Seems like two problems - Could this be a bad thermistor due to working too good.
My thought is the board may be bad. Because the fridge should prefer 120 when electric is present. Ingitor sparks when LP is lit and when 120v element is cooking too.
Yes, that would point to a bad board. Since the unit runs on 120 that means the Board is SEEING the 120 and should lock out the LP system. PLEASE respond with year model of RV. Doug

RE: Class A's in Australia are mostly Conversions
Nice! Tiffin Motorhomes has been exporting an Australian right hand drive version of their Allegro diesel pusher Class A's from the US for the past dozen years or so.
Tiffin Exports to Australia are LEFT HAND. The Importer modifies the steering when it gets to their shop. IF they do that at all. I have worked on Tiffin exports that have had a malfunction while in transit from Red Bay to the Los Angeles shipping port. Inside they are also NOT complete, with various parts shipped loose inside. Doug
PS. I attempted to look at a Australian Tiffin but the only pics was a Breeze with the steering modified to the Passenger side and the entry large door on the drivers side. So, they do modify the steering on Tiffin exports in Australia

RE: Onan Generator connection to 4x4 junction box
The 10 gauge goes to the Motorhome 120 breaker panel. The 12 gauge goes to the Rear AC. The Black with yellow usually goes to the rear AC(the 12 gauge) and is on the 20 amp breaker on the Genset. The other black wire comes from the 30 amp breaker on the Genset and goes to the 10 gauge. Doug

RE: No gas to stove only
Here ya go. I taped them together as all they did was silicone them in place and they fell off. It's a normally closed solenoid. Place the two pcs together and you hear the valve open. With the two pcs separated the stove will NOT light. The switch was mounted to the arm that raises and lowers the Quartz top.

Thank You, Nice and easy design. But from your pics it is obvious Mobile Suites designed and installed the system. VERY RARE, but I rarely work on Mobile Suite type RV's. I guess they rarely break down:) Doug

RE: Water heater Anode
On Suburban water heaters, the Anode is REQUIRED. It is a sacrificial part that takes the hit for water induced corrosion. When you do your annual maintenance(Yes, you need to do this) you will see the rod has gone from about 3/4 diameter to les than 3/16 inch piece of rod. That shows it took the hit instead of the interior of the water heater. There is no good reason to have a spigot in place of the anode rod. It is not that hard to remove and reinstall. If the rod has been completely destroyed in a year you need to do a check every 6 months. Use this to seal the threads. Doug

RE: No gas to stove only
Does the cooktop have a lid that is fixed at a hinge point? If so the switch may be faulty or came loose.
Please explain this comment. I have 44 years as an RV tech and have never seen a RV cooktop cover that has a "safety" switch. Kind of makes NO sense. To light a cook top burner you have to lift the bi fold cover anyway. Doug
My Mobile Suites has a motorized lift on a switch for the Quartz top because it's HEAVY and it has a switch that closes off the gas when it closes plain and simple.
Can you give me the brand and model number of your stove? You have a luxury model RV and those may have appliances that have either been modified or the RV maker has installed an optional system to prevent damage if the top is lowered when burners are on. While your comment made me think, think of you owning a Rolls Royce and commenting on a standard automobile forum about items in your Rolls Royce. Completely different items and way of operating. The OP stated Jayco, as a Jayco center, I KNEW there was no such thing as a safety switch for the Stove. Doug

RE: Awning not working right
Weatherpro awning that has your symptoms indicates a bad motor. It is tripping the excess amp control. To manually retract, you disconnect the motor wire plug from the controller and apply 12 volts to the 2 wires. If the controller is not easy to find, you can also disconnect the quick connect at the motor and jump the 2 motor wires with a 12 volt battery. I use a 12 volt Computer battery back up(UPS) battery to do this. Doug
PS, there are 2 motors the Weatherpro uses. Depends on if you have the intergrated roll down patio screen as part of the awning assbly. Roll out the awning and get the Model/Spec/serial number before it finally fails.

RE: No gas to stove only
I'll give that a try. It's bot in a slide out so I can't imagine the hose got pinched. We were on the way home from a 2 week road trip where it worked fine. Luckily it waited until the drive home to stop working
Is the supply hose to the stove top Rubber or Copper? Let us know if the LP flow test I mentioned spews LP or not. Doug

RE: No gas to stove only
Is the stove in a slide out? If so, odds are the rubber LP line is pinched. The regulator you see drops the Supply from normal 11.5 inch water column to 10 inches. They rarely fail. They do leak sometimes but rarely fail to deliver LP. What you need to do is, TURN OFF LP AT TANK. Disconnect the LP line from the regulator on the stove. Then while holding the LP line have someone turn on the LP tank. IF the LP spews out turn off the tank. IF NOT, the pinched hose is the problem. Doug

RE: 2005 Norcold refrigerator -- shore power not cooling
Since unit doesn't work on lp and marginal on electric, test the thermistor.
Thermistor testing
Potentially bad circuit board. I prefer Dinosaur Electronics replacements..
A BAD thermister will test GOOD most of the time. If my checkout shows a good refer, then he needs to replace the Thermister. Doug

RE: 2005 Norcold refrigerator -- shore power not cooling
N821 has just 1- 120 element.
1. Verify ventilation from outside lower refer access door up thru the roof is clear of obstructions. You will have to remove the top roof vent to verify upper area. Just 4 screws removes it
2. Verify your model does NOT have a 12 volt cooling fan just below the rear condensor coil. Step 1 with a flashlight will verify that.
3. If 1 and 2 check out, you then disconnect the 120 heat element from the rear control board and run 120 volts direct to the Heat Element for 24 hours. IF after 24 hours the freezer is NOT below 10 degrees and the lower refer is NOT below 40 degrees, your Cooling Unit is bad and needs replaced. Doug

RE: Norcold Refrigerator will not run on 120-volt power.
Check the back of refrigerator see if a red light is lit on the temp limit switch. If so you need a magnetic to reset the switch. Search youtube for more info. Mine was a Norcold 1200.
The recall switch shuts the complete operation of the refer down. NOT just certain parts. Doug
