Question about Heating & Cooling

Camper hasn't been used for a few months. Now the air conditioner won't kick on. Had same problem last year. Took to repair shop. The repairman removed the cover and did something and it worked fine. We don't know what he did.

    We have checked what you suggested we check with the exception of the capaciters.

    Unfortunately we don't know enough about air-conditioners to know where the capaciters are so it probably isn't safe for us to try to find them.

    We feel certain that this is the same problem we had last year. We do remember the repairman saying that that was a common problem if the air-conditioner hadn't been operated in some time. He mentioned looking for dirtdobber nests but also said there were none. I'm not sure these were his exact words but as I recall, he said it had just "siezed" up. To us it meant that it had just locked up from not having been used. No parts were required.

Simply disconnect the AC from power and plug it back. If you have a 30 amp fuse on AC you may remove and put the fuse back.

If that does not work:

Check if there is a relay for the AC, in that case you may need to replace relay.

Ensure that the battery is fully charged, and th, at the inverter is working fine. The camper air conditioner (on US model) requires 120 volts +/- 10% to operate correctly.

There are also two capacitors located on top of the compressor, run capacitor and start capacitor, if one of them has blown the unit will not start. Be careful handling the capacitors, they can release heavy discharges even when unit is not connected to power.

Welcome to FixYa
Not enough cooling complaints are due to air flow issues, and not lack of “Freon.RV air conditioner- come from the factory- are hermetically sealed.The first basic area is the air filter. In summer, using the RV and air conditioner around the clock, the filter should be checked weekly and cleaned as needed. RV air conditioners use either a foam type filter or a fine mesh, both of which can be rinsed in water and reused.keep the filter(s) clean.Few years latter even the best filter will let enough dirt past to coat the evaporator coils, though, so they need to be cleaned. If the coils are not too dirty, and if the installation leaves enough room to access the coils.Once the cover is off, you can see the evaporator coil -Clean Coils too...

You hear the compressor kick in (Hum) but no fan comes on? Will the fan come on when just in fan mode, not cool, or do you have that set-up?

When turned on, the unit sounds like it will start then turns off within a minute.

Presently according to my information there is no recalls for Fedders products at this time for this model type.
