RE: Dometic dual zone thermostat no power
.1. PHONE cord is NOT wired correctly for a RV communication system.You cannot use a Phone cable.
2. The POWER for the wall CCC2 comes from the Zone 1 AC control board. You don't state year model of RV OR Model number of AC. BOTH are important
3. The usual cause of intermittent and now a dead tstat is the modular plug in ends RJ11, have corrosion at Zone 1 and/or Zone 2 if you have 2 AC units.
4. REALLY need model number of AC unit. Doug

RE: Replace Girard tankless how water heater
Now, to the problem he has. Believe it or not, ANY possible air in the pressure plumbing will cause erratic operation of a Girard. This means, if you have a washer/dryer prep and you have NEVER opened the 2 valves, there is air in that part of the system. Outside shower, never used or not run after winterization. Air there also. So, open every possible valve you can find and let the air bleed out. Including the 2 winter drain valves. See if that improves the operation. If not, then replace with a standard water heater. Doug

RE: Dometic Gas/Elect Water Heater Sometimes Does Not Work
Next time it happens, do NOT remove the plugs. Push them gently left or right at the same time. IF a bad connection this will cause the W/H to operate. I would suspect a BAD Board, not the connection. Doug

RE: New Suburban Water Heater Won't Light
1. NO such thing as a Pilot light, on your model. Just a standard flame.
2. You need to post Model number of the new W/H
3. Also, the W/H has a tri start board. It will try 3 times to light with pauses of about 15 seconds between attempts. Does it do that?
4. Turn the gas OFF, attempt to light and let it go for 5 minutes. DOES THE RED LIGHT COME ON? It should. If not, you may have miswired the new heater. Did the NEW W/H come with the same color 3 wires as the old one?
5. It could be as simple as a bad Ignition module. Doug

RE: thinking of buying a Motorhome....looking for tips/hints
Factor in cost and depreciation. Once done, you will find it is BETTER to rent the type and floorplan you want for 1 or 2 weeks. KEEP renting different types and floorplans, until you find your fit. THAT will get you the knowledge of what you want and can afford. BUY without doing this will cost you tens of thousands of dollars if your RV does NOT meet your expectations. Doug
PS In the RV sales and service for almost 50 years. You would be amazed how many first timers take thousands of dollar hits when they buy and the Floorplan does NOT meet what they thought they wanted, and then they trade.

RE: Dometic 2862 refrigerator at 9200' elevation...any issues?
From Winnebago. Granted, the LP usage of a refer is minimal compared to a water heater or stove or furnace. But, if your LP regulator is not set to correct pressure, then a high altitude will impact the refer. It will NOT stop cooling, but its performance will be impacted. Doug
"While many people love to use their RV to go on trips to the mountains and other high-altitude locations, it is important to remember that with higher elevations comes some potential concerns for using your liquid propane appliances.
Problems arise because at higher altitudes, air contains less oxygen. For a flame to keep burning, it requires the right mixture of fuel (propane) and air (oxygen). Too much or too little of either and the flame will go out or burn inefficiently. Without a sufficient flame, your appliance won't work properly.
Ways to Combat High-Altitude Issues:
Check for high-altitude adjustments. Your first step should be to consult your operator's manual for instructions on high altitude operation of your specific appliance. This should have warnings and recommendations for usage. For example, some appliances have an adjustable air intake to adjust the air/fuel mixture when necessary. Depending on how high above sea level you are, you may be able to adjust the air intake.
Try a smaller orifice. If your appliance doesn't have an adjustable air intake, you might try a smaller orifice. At high altitude, there is not enough air getting to the appliance to create the right air/fuel mix, usually creating a lazy yellow flame and soot deposits. In this case, a smaller diameter orifice could limit the amount of fuel and create the correct air/fuel mixture.
Get a kit. Some manufacturers provide special "high-altitude kits." Please consult your specific appliance operator's manual or contact the manufacturer of your specific appliance to see if they have a kit available.
RVing is a great way to see many different areas, just make sure you are doing your research and taking the necessary precautions when traveling to places that pose specific challenges. Happy travels!"

RE: Dometic AC freezing up
I hope you are honest enough to report when you do find the problem. As I stated, I have NEVER--NEVER had a control board have a problem with freeze sensor. It is always the freeze sensor. In the past 25 years since Dometic came out with the electronic freeze sensor system, I have probably worked and FIXED in excess of 500 Dometic AC system controls. Doug

RE: Dometic 2862 refrigerator at 9200' elevation...any issues?
Elevation WILL affect the BTU's of the LP function
Out of correct level WILL affect operation of the cooling unit system. So, you have 2 anomaly's that are causing a problem. Doug

RE: Dometic fridge help. Please!!!
Almost ALL Dometic 3 way Refers, the 12 volt option, there is NO THERMOSTAT control for the 12 volt heater. The Refer uses the 12 volts ONLY TO MAINTAIN the existing cold in the refer WHILE IN TRANSIT. The reason is, the 12 volt element pulls a lot of 12 volt amps and while in Transit, the towing vehicle or the Motorhome will supply needed 12 volts from the Engine. The LP and 120 ARE controlled by the tstat. There are some OLDER Dometic's that do control 12 volt with a tstat, but they have not made those in over 25 to 30 years. Doug

RE: Dometic AC freezing up
My problem is in the living room. The one in the bedroom works fine. I swapped the two stat and the problem is still in the living room. Therefore I'm certain the thermostat is not the problem.
Swap the freeze sensors (front to Rear/Rear to front). Even tho you replaced the one. Let us know. According to your posted Model number it is NOT a HP, just a standard AC. Swapping should be fast. Doug

RE: Dometic AC freezing up
The EasyTouch RV 351 thermostat does read the freeze sensor. They call it Inside Coil Sensor. In there manual it says "Temperature of inside coil has dropped below 30°F (-1°C). The compressor will turn off and the fan will run until the inside coil sensor temperature reaches 54°F (12°C)."
That is what the THEIR manual states. BUT, since YOUR system is malfunctioning, I still state YOUR Tstat is the fault, NOT the Dometic controls. The original Dometic CT Tstat DOES NOT have Freeze sense capability, to sense or display Freeze sensor. It only has 3 wire control and all communication must come thru the 2 wires of the three. Now, are you POSITIVE the "Coil Temp sensor is NOT the condensor sensor for a Dometic HP? The Dometic HP DOES have an external condensor coil sensor for freeze up in HP mode. THAT sensor may be your problem and not the freeze sensor for the COOL mode evap. This sensor if defective WILL cause lack of compressor operation. THIS is why I tell you to call Easy Air. WHY will you not call easy air? Doug

RE: Dometic AC freezing up
Since I have no knowledge of the Easy tstat, I looked it up. ANY Dometic wall tstat NEVER had the capability of reading the freeze sensor temp. I checked all the Dometic Easy air replacements and NONE had a spot for Freeze sensor capability. So, You need to really call easy air and get help. Doug

RE: Slide Out Issues
Just got a call from CW Service advisor. They are not going to charge for the diagnosis and in fact they are not charging for a small job they did that I waws happy to pay for. So now all I need to do is find a shop that will work on a 20 year old slideout system. I've been referred to Timbuktu in Worcester. Not sure if I'll try to get it fixed now or in the spring.
You better start now. HWH is way behind in replacement parts. It may take a few months for the shop to get the replacement parts to fix. Spring, the shops will be very busy. Doug

RE: Dometic AC freezing up
Doug
I have seen the coils ice over.
I swapped the stats and the problem did not follow.
I only have the problem on 1 unit the other 1 is working fine.
Kenny
You need to contac the Tstat maker. I have NEVER---NEVER had a AC control board malfunction for a freeze sensor. It is ALWAYS the freeze sensor malfunction. Try swapping the good sensor from the other AC unit.
Is your control board in a 6 by 6 galvanized box? If so, I would swap the control units. Very easy to swap. Since I never work on systems that have modified parts(your after market tstat system), you really need to contac Easy air. With Dometic Control and tstat, I have NEVER had a problem like yours. The aftermarket tstat system makes troubleshooting much harder. Doug

RE: Dometic AC freezing up
If you are getting icing you likely have an an airflow problem. Is evap. coil clean? Filter clean? Duct work clear and ALL registers open? Ceiling assembly installed and sealed correctly?
IF you have a functioning freeze sensor system, you WILL NEVER get ice regardless of conditions. Doug

RE: Slide Out Issues
FYI, 310 is the Model of the Jack system. While the slide mechanism is HWH that is not the model of the slide system. Your HWH slide system is one of the easiest to diag and fix. The fact that CW and some other shop could not find and give a diag in less than 1 hour shows the state of incompetence in the RV industry service industry. If the jacks and other slide operated and just the one did not retract, that points to the solenoids(2) for that slide not operating. There is a extend solenoid and a retract solenoid. EITHER could cause a retract problem. BAD valve(not releasing electrically) or 12 volt supply to the solenoid problem. Good news is, a GOOD shop can get hold of HWH and get diagnosis help. HWH prioritizes authorized shops for Phone technical help. Doug

RE: Dometic AC freezing up
1. That tstat is NOT a Dometic wall tstat. That is an aftermarket tstat.
2. You need to contac the Easy touch people for help. The freeze thermister WILL READ the evap and it will get below 60 degrees.
3. The AC only holds about 1 lb of coolant. So, if a leak, it will leak enough to NOT freeze or even cool.
4. Remove the sensor from the evap. Unplug one wire from the control board. IF the compressor comes ON, leave it that way. If not, jump the 2 wires together and leave and observe operation.
5. Have you actually seen the coils covered in ICE? Doug
PS, SWAP the wall stats and see if the problem follows.
Do BOTH AC units do this?
