Front A/C Issue
Our trailer is used seasonally and about to be opened up again for the next 8 months or so.
I ran into a problem with our front A/C last summer and am about to look into it again for this season. If the front A/C is set to cool with fan on automatic the compressor starts and runs (without the fan running) for about 30 seconds then simultaneously the compressor shuts off and the fan comes on and runs for about a minute. 10 minutes later the cycle repeats. Without the fan running the compressor builds to an excessive pressure and is shut down for protection. If I set the fan to run on high prior to switching it to cool the fan will continually run and the compressor will cycle as needed to maintain temp. The only way to get cooling from the unit is to have continual fan operation.
In an attempt to correct the condition I have replaced both of the capacitors as well as the circuit board within the unit. Additionally I have reset the thermostat.
