DuoTherm Air Conditioning Concern

Hi everyone,

I have another problem with my airstream. The air conditioner is a DuoTherm. The problem is that the a/c cycles back on too early. It cools excellent and when it cycles off, it will recycle back on within 15 seconds. The problem with this is the compressor get lugged real bad and then it cycles back off in about 10 secs. It usually takes a few minutes to come back on. When it does, it comes on normally and cools. I am afraid the short cycle off time will damage the compressor. Any ideas would be helpful. My Airstream is a 1969 Sovereign International 31 foot. I would call and get someone to look at it, but, it is located in the country at an RV park and is permanently parked right now. Thanks for any help.

Amp draw.............

.....................on the compressor hot lead is the only way to tell if you are low on R-22. Remove the cover on the roof and remove the panel from the control box on the right side of the unit. Find the hot lead going to the compressor and....... BE CAREFUL HERE!!!!! ...........with the unit running in cool mode, place an amp clamp around the hot lead of the compressor.

Let me know what reading you get and PM me with the info and the model # of the A/C. I'll look up the rated amp draw and let you know what's up. Also record the ambient temp outside when you do this.

And while you're up there, check the condition of your capacitors and PTCR.

If you check the amp draw, and Lew says it is good, you can move the sensor for the thermostat, and if that doesn't work, you can put a thin rubber sleeve over the sensor for the thermostat. I did this with my Coleman, and it helped a lot. This will only help if the A/C unit is in good shape otherwise, and the sensor is in the flow of cold air.
