I have a duo therm a/c roof top unit that is not cooling properly it has been approx 2 years since the unit has been run I have checked breakers and fuses in breaker box I removed the cover from unit the compressor is running and getting hot the lines are cool but not cold the fan is running I am thinking that the unit is low on freon can some type of self tapping ports be installed to add freon or have ports soldered in place or could there be another underlying problem that can be checked or is it best to replace the unit

You have a leak in the system that needs repair. If you have to add freon to system there is a leak. You need a service tech to do the repair. If it is out of gas you may to replace it. Leaks do not correct themselves. Russ

Duo Therm A/C (2009 Sabre RV) won't shut off


bad compressor relay on control board. The relay is not opening the circuit, allowing the compressor to stay running when unit is turned off. This overheats the compressor and opens a thermal disk shutting the compressor off. When thermal disk cools down, the compressor restarts under load and trips breaker.

Duo Therm AC/Heating not working at all after tripped breaker.


I had to get on the roof of mine, remove the cover and manually spin the fan. Add a little oil to the shaft where it goes thru the bearing. All of this is done on the roof side. Mine required this procedure every spring. Duotherm realizes they had a problem and have since corrected it but they don't deal with all of their customers that had the original problem.

Location of Drain holes on Duo-Therm Model 630035.321


Good place to start is up on the roof. Look way under the unit (hard to see some times) along the bottom, between where the gasket sits on the roof and metal bottom of unit. Should see small round or similar sticking down from unit. There will be a hole in the side of them. Poke around with a wire or something to open them up. If you don't see water/condensation running across your roof from unit when it's operating, (usually in 2 directions, 1 each side of unit) then yup, there plugged.
