SOURCE: RV air conditioner. Compressor running, fan stops before cool

The fan motor is getting hot and going off on the internal overload in the motor.
This is caused by either a low voltage, a bad capacitor, or tight or dry bearings in the motor.
To check the bearings turn the power off to the unit, then spin the fan blade if it spins freely then the bearings are ok.
To check the capacitor you will need some kind of tester or you can buy a capacitor and replace it, that's what a lot of people do. They usually don't cost very much.
To check the voltage you will need a voltmeter and measure the volts at the unit.

SOURCE: I have a Dometic RV fridge that wont get cold. it

It sounds like your cooling unit is going out. Here's a couple of things to check. Do you smell any ammonia when you open either one of the doors? When you look at the rear of the fridge, do you see anything that looks like rusty water that has run down any of the metal tubes and dried up? If the answer to either one of these is "yes", then youll need to start looking for a new fridge or replace the cooling unit on the one that you have.

SOURCE: Dometic rv fridge runs fine on elec, lights on gas

It is key that all control switches are in the correct position, depending on what power source you are using, gas, electric, etc. If the switches are not in the proper setting, the unit will not operate.

Here's the manual for your fridge that should be printed out for your use and reference (and reading enjoyment). It has all the info needed to operate and troubleshoot it.

Typically, when using any gas appliance with a pilot light, the sensor has to first be hot enough to trigger it to allow the safety gas shutoff to open and allow the gas to flow to the pilot/burner. Follow the instructions and you should be all set.

Largest problem is with the cooling unit going bad on these unit at about your units age.
But first
check your 12 volt fuses and make sure both the fuses in the back of the refer and the fuse in the power distribution panel are good
Must have 12 volt for the gas to work

Installing a Dometic single zone LCD Thermostate in my rv. Getting a code E1. Everything seems in the right place. Is there something the instructions for got to mention? How do I get it to work?


Try this.
Turn off thermostat. Wait for no display on lcd.
Hold + and mode at same time for 3 seconds.
Lcd should display - -
Turn on as usual.
If that dosnt work you have a cabling issue between thermostat and main board. Possible bit rare component failure. If all is installed correctly.

I have a duotherm rooftop ac. fan runs fine but when comppressor starts it runs for 5 or 10 seconds and shuts down


I'm not familiar with these units so this is very general. Your compressor could be shutting down due to low pressure. You would need to get the refrigerant charge checked. It might be due to an overload tripping, which would then reset itself. If you had a schematic or something to send me I could tell you more.

Ac starts kicks on and off every couple mins


Sounds like the compressor is the one making the "NOISE". If the sound sounds like something trying to start, then kicking off, its probably the compressor and not the fan. Hence no cool air.

Relay (?) sticking Dometic RV rooftop AC


Go up on the roof of the unit and remove the AC Shroud. With the unit running, see if you can pinpoint where the sound is coming from. The only thing on the entire AC that would make that much of a vibration would be the fan motor. Not sure what would cause the fan motor to do this. The compressor may do that but only if the windings are bad and then it would not be cooling.
