Heat Pump Troubleshooting (Advice/Help)
I need some heat pump/hvac help - advice. Let me preface this by saying I know very little about HVAC stuff, esp heat pumps/ac.
Trane WeatherTron xe800 air-source heat pump. 9-SEER ?-HSPF
A few times this month the outdoor unit fan has stopped rotating and there is just a humming sound. The "porcupine" coils inside the unit would get warm, but the compressor isn't running (or doesn't seem like it is).
I took it apart cleaned the debri out and it "magically" start working again. Well, it happened again yesterday. We noticed the inside of the house getting cool and sure enough the outside condensor fan had quit. I flipped the breaker off - checked some things - the coils were hot, plus steam was coming off the unit.
I flipped the breaker back on and just started humming again, so I gave the fan a manual turn and it started working. The compressor kicked on, the fan spun up to speed and the big line going in to the house warmed up. It worked the remainder of the day and was still going when I left for work this morning.
Any idea what might be going on? - The fan going bad, bad connections, I guess I was really surprise that the condesor fan somehow also controls the compressor?
The unit is 21 y/o, so I know its on its last legs, but I'd like to try and get by the rest of the winter, thats another expense I DON'T need.
What is a rough price for new replacement?
I think the EPA (yea for our govt) says swap-outs have to be 12SEER, so I guess I may have to swap the indoor evap coil also?
If I have to replace more that just the outdoor unit, what other companies are good (York, Carrier, Rheem, Goodman).
It's my understanding that it isn't good idea to mix different types of indoor & outdoor units - York outdoor & GE/Trane indoor (I assume they mean the evap coil is the indoor unit)
Any help would be appreciated!!
