Dometic Rv Heater Not Working

Dometic rv heater not working. If you see soot on the outside of the rv by the exhaust vent, check all vents. I reached out to my contact at dometic who said that your dometic/atwood g6a8e water heater (new part is # at96121) either has a bad control board # at91367 or bad electrode. I am trying to follow the atwood / dometic troubleshooting steps (found here).i removed the panel under the kitchen sink and see this on the rear side of the tank:

No spark when on lp mode and no heat under electric. Opened it up and the fault code says ignition lockout fault. To fix this problem, remove the cover and start cleaning the switches.

What is the make/model/year of your rv? Jayco, jayflight slx baja 224bh 2021. Carefully remove the orifice and see if you can blow through it.

Ours works very well to take the morning chill out of the mh or to warm the bedroom before sleep. The freezer may still have some cooling. If not, your tanks are probably needing to be refilled.

Here is what you will need to check: Finally, get your multi or voltmeter out, and you do not need an expensive one, and check to see if the electricity is flowing as it should. Have you checked the coolant level?

It worked briefly and then stopped. Our water heater quit working, so i took it upon myself to get it working again.#swagnation #jointhepack want to save money on your next fuel stop? Has there been any leaking from the hoses?

An alternate method, if you can work safely with electricity, is to disconnect the electric heater element and wire it directly to 120 volt cord and plug it in and let it operate overnight. Once the hydrogen is lost, 2nd stage cooling (the fridge section) pretty much stops dead. Pressurized freshwater is reaching the inlet of the water heater.

If it does turn on and keeps a steady flame, then your gas lines to the furnace may be blocked. Checked the forum, and then turned the propane off then on slowly. If it’s a tripped circuit breaker, reset it.

If water comes out, it is not a supply problem. Another great rv heater troubleshooting tip: Please note that you need to have a professional service come out to test and tell you which part needs to be replaced.

If the thermostat has no lights showing, it means it is not receiving dc power. Then it might be quite frustrating for you to continue using your device. If your rv is as cold as the 30 degree air outside, the heat strip air is not going to feel warm even though the heater is working, it moves more air and will warm the whole rv not just the space in front of it like a ceramic heater.

Your rv, here’s a list of things you can check before you call for a technician: You can check this by standing by the open heater access panel while someone turns on the switch for gas. I confirmed power to the board and swapped out the control board with no luck.

You may also want to look at the If you see soot on the outside of the rv by the exhaust vent, check all vents. If the fridge cools in this by pass mode, the heater element is ok.

When it comes to this, it is important that you first confirm that something is wrong with the water heater itself instead of other equipment. Otherwise, it could be a tripped circuit breaker or a blown fuse. In fact, the first phase of failure is often a pinhole leak in which the hydrogen gas component of the coolant leaks out, and hydrogen is odorless and colorless.

I don't have the compass connect but on our second trip out our electric side stopped working. If when you turn the switch on, and listen at the heater for the ignitor [clicking] if you don't hear the ignitor, then there might be something stopping the spark. Plenty of water in tank.

Moved a few hundred miles up to sc and now neither gas or electric work on the wh. Start by verifying the problem is not an issue with supply. If the buttons on your dometic dual zone thermostat seem not to work, this may be caused by too much dust which has accumulated inside the thermostat or on the buttons.

You will have to pull the cover off the hot water heater on the outside. No tripped breakers, reset them all 3 times. If your device is faulty then you will have to contact the support team for dometic.

Sometimes it is just the simple turn of a valve at the water heater itself.
