I have a heil 2 ton heat pump system. Over the past month I have had my system not produce any heat when turning it on. After turning it off for about 10 minutes and back on again...poof!!! HEAT!!!
The heat pump was off the whole day. I arrive home at 7pm. Outside temperature each time was in the low 40s dropping to 30s. I turn the heat on, wait.....and hour later no heat, two hours later no heat. So I turn the unit off, wait 10 minutes and turn it back on. BAM!!! Heat! I have already had the capacitor replaced this summer as a precautionary measure. It is a dual run capacitor. I would like some suggestions to what else may cause such a situation.
