I have a GMP075-3 that was installed in approximatly 1993. I recently bought the house with that unit. My problem is that when using the A/C, the blower will not start periodically. It will work fine for a majority of the day but at times the inside unit will make a humming noise for approximately 20 seconds and the blower will fail to turn on. The humming noise will then stop. A simple but not permanent solution that I found is to spin the blower turbine with my hand. Then when I turn the unit back on it will fire up fine, however it will eventually stop working again. Any help? Possibly a Capacitor problem? If so what side capacitor does my unit use?

Return Air Vent or Vents Inside Coil Box Underneath Furnace (Will have a small access door) Filter Box Attached to Return Air System
A lot of people still look for their filters inside the coil box, but more recently installed units will have them in the return grills inside the house. Follow your return air from the vent inside the house back to the unit and it will be somewhere in between there. Hope this helps!
depending on the brand and if he had to recharge and pulled oil oiut of compressor it can cause comp to be load. goodman is also a lower end unit and you pay for what you get. it is a very reliable unit howvere
I'm not sure of the kilowatts. The 10 min on and 5 off is telling me there is to much heat by the thermostat or you house needs more insulation. The new compressor is designed for more efficient run time. The other thing is the unit to big for your house? It should run 10 -15 min when low humidity is in the house. Otherwise longer if its pretty warm inside.
ok...where to start.lol ....the thermostat is just a switch.It will tell the unit to run or not run.if you measure the temp with the heatpump running,the air is warmer than 68 but it feels cool to you because your body is 98.6.The unit will run more often and for longer periods when the temperature drops outside for a few reasons.First,your house has more of a load to heat,meaning you have more heat loss because of the difference in temperatures outside and inside.Second,your heat pump pulls heat from the outside air.The colder the air outside,the less btu's for it to pull.If you have anymore questions firstname.lastname@example.org Hope this helps,Dave
