If your ac is blowing out hot air then the first step is to check the thermostat.
Rv fridge not working on ac.
Check on the airflow.
This sediment will hinder the ability of the ammonia to circulate properly through the cooling unit.
The altitude can put a strain on liquid propane.
The 110 volt circuit breaker may be off or tripped.
As rv refrigerators age the ammonia liquid can create sediment that settles to the bottom of the cooling unit.
The cooling effect from most rv refrigerators originates in the freezer compartment and then goes into the main compartment.
So if your freezer is working but your main compartment is not you likely have reduced airflow.
No ac power to rv check that there is power to the shoreline receptacle.
Electrical power does not work.
First check that you are getting the energy to your refrigerator.
That means if the evaporator coils are clogged with frost it would prevent airs from passing through and reduce the cooling effect of the refrigerator.
In the case it appears that the coils have too much frost on them you should use a hairdryer to apply hot airs to coils.
The air conditioner blows out hot air.
Use thermometers designed for use in refrigerators.
Check your circuit breakers and fuses.
Check circuit breakers and fuses but most importantly you need to check the outlet at the back of the refrigerator to make sure voltage really is there.
Check circuit breakers at power center.
If this has already happened you can fix it.
If your rv fridge works on gas but not on 110v ac then try this.
So the first thing you have to do to solve the rv refrigerator not cooling but freezer is issue is to assess the evaporator coils.
Rv air conditioner troubleshooting 2.
If you fail to make the switch as you approach higher altitudes your burners can well burn out.
More often than not the problem with an rv refrigerator is time combined with lack of use.
Rv refrigerator exhaust blocked there is also a fair chance that the hot air generated as a waste and side product of the cooling process is not able to find a path and a way out from the exhaust vent.
The first step is to verify you have 110v ac at the refrigerator.
It s best to use one in each compartment.
