I ruined my dash ac condenser (side mount at back of engine.) I've got a call into Foretravel Parts but no answer back. It is the 12,500 BTU system and the condenser is 18x18 with two rows of 16 coils. Leaving for 6 weeks at the end of July. Have found a local garage that will replace it and the dryer.
You should be able to Google air conditioner condensers and find a close match. I don't think there's anything particularly special about the ones in our coaches.
A couple of excellent automotive air conditioning forums are the following:
A/C Forums - Automotive Air Conditioning Bulletin Board (https://forum.aircondition.com/)
Automotive Air Conditioning Information Forum - Index page (https://autoacforum.com/)
They might be able to point you to good sources.
I thought they were all 17,500 btu ac's?
Yes, 17,500 btu.
Sourced from FOT. They had it in stock.
