No fan, No A/C, Heat is Fine!
Intertherm / Nordyne Model # FEH-017HA-04. Last fall we replaced our thermostat, I believe the fan was non functional then.? We are gearing up for summer and running checks. When placing thermostat to fan or A/C we have neither. The blower will run with the manual switch inside furnace. Fuses outside at condenser are good. We are not sure what to replace or do next? Our breaker reset did no good either. Not sure about blower relays, and contactor relays or if these are one in the same. Diagrams of our model would help!
Hi,
Did it work last summer ?
When you set furnace switch to fan on, the blower works correct ?
When you have furnace switches set to cool and auto, nothing works ?
Does your t-stat have a heat-cool-off switch ?
If so, is it set to Heat ?
The blower relay controls the blower for cooling mode and the contactor controls the condenser fan and the compressor.
With All not working, probably a loose/broken wire or wrong setting at switches.
Thanks,
Robert

Some people are Humbly Grateful, while some are Grumbly Hateful.................... Which one are you ?
To my knowledge it did not work last fall. When the thermostat is set to fan, the fan does not run. When we set to auto and cool it does not run. It will only run on heat setting. or by turning on the switch on the blower on.
Hi,
First step is to stop replacing parts until problem is located, will save you some $$$$$$$.
How many wires are connected to your t-stat ?
IF it is only two, set t-stat to HEAT, then set temp where you want it, then set furnace switches to COOL and AUTO.
IF it is more than two, either the transformer is bad or you have a loose/broken wire in low voltage circuit.
