“Induction draft blower Amana HE 90 furnace” , posted Sun 13 Jan 17:27 ______________________________________________________________________ I woke up the other morning and discovered I had no heat. I called to have this checked and was told I needed to have the ID blower replaced at a tune of $289.00 just for the part itself! The furnace is approximately 10 years old. Does this sound accurate? or did I get the shaft? thanks Replies: yuri “Re(1):Induction draft blower Amana HE 90 furn” , posted Sun 13 Jan 18:38 ______________________________________________________________________ Sounds reasonable. Plus labor. Also depends on the cost of living in your area vs other areas. Yuri

“Heat Pump Problem-Compressor Shutting Down” , posted Thu 1 Nov 11:19: ______________________________________________________________________ Hello, I have looked through your forum but havent found a similar problem. I have a Goodman CPLE48-1C heat pump and a Goodman ARUF048-00A-1A air handler w/1 heat strip. The thermostat is a Honeywell RTH3100C with the following wiring. E-No wire Aux-Blue Y-Yellow G-Green O-Orange L-No wire R-Red B-No wire C-White Option 6=9, 8=9, 14=0. The system was installed late Spring of this year. The cooling portion has worked well and still does work. We recently had a cooling off, so I decided to try the heating side. The system seems to work normally when it is turned on, but after approx 50 seconds, the outside unit shuts off. The air handler continues to blow for about a minute and the shuts off. The thermostat shows a blinking Heating for about five minutes, and then the cycle starts again. I read the thermostat literature, and the blinking Heating indicated the system is in compressor protection mode. If I switch the thermostat to Emergency, the fan blows normally and the compressor remains inactive (I believe this to be normal). Any suggestions would be greatly appreciated.

Verify common at your air handler. You should also jumper Aux to E (after proving white is Aux) “Tip of the Day” Remember to remove power first.
