Coleman Airxcel 48000 series 15KHP
My rig is going on 6 years old in March. The rear roof hvac unit is an Airxcel 15k heat pump and has work well until now.
We were in NE GA at the end of October and used the heat pump in cold weather just fine until needing to switch to the furnane.
In route home, we stopped S of Atlanta and stopped overnight (55 degree weather) and I switched on the heat pump. It ran but no heat.
The RV has been parked at home since until today. We arrived at our destination and no heat. 62 dgrees outside. I switched to ac and lowered the thermostat. The unit came on but was only blowing ambient air.
So the unit will run with the thermostat set to either mode but will not cool or heat.
I ordered and have received the run capacitor and will try to swap it this weekend.
This unit has 2 capacitors. One is the run capacitor and the other the fan. The fan is running in both modes so I assumed its ok. There is also another part in the that the parts diagram shows called a "OD Temp Relay Board" which looks like a clear covered relay.
I ordered the run capacitor and replaced it last weekend. No change at all.
I'm not an electrician or electronics guru but do have mechanical abilities. I read up on discharging capacitor prior to replacing them. When I attempted to discharge the original capacitor, I did not see or hear any spark.
I assume the fan capacitor is ok since the fan will run in both modes so it has not been replaced.
I ordered the relay and a fan capacitor as well and hope to get those replaced in the next few days starting with the relay.
Any suggestions in the meantime would be appreciated. Thanks.
