How old is the heat pump and what model is it? What part of the
country do you live? Let me know if you need heat pump prices. Thanks

I have a 15 year old FHP geothermal heat pump, the compressor won't
start. In heat mode there is a slight humming, and every 30 seconds or
so louder buzzing noise for a few seconds. The compressor is getting
220V to the contacts, the resistance between the then is in the range
of 3 to 7 amps. I tested the start capacitor with a simple DMM using a
resistance and volt modes, seems to work as it should. Any ideas? Time
for a new heat pump? Should I try a new start capacitor anyway?
