Nordyne MGHA-056AAFC-02
Thermostat works fine.
Burner may have low flame.
Blower takes about 5 minutes to come on.
Forced air out of ducts is not as warm as it used to be.
What is the problem with slow & low heat ???

Sounds like the burner isn't kicking out the proper amount of heat. Make sure your orifice isn't plugged and that the gas valve is receiving gas at the proper pressure. If all that's OK, then you may need a new gas valve. http://www.aberdeenhomerepair.com/store ... ilot-light

I tried to blow out any obstructions (spider webs) in the burner tube
with compressed air.

I replaced the thermocouple. Pilot light works fine.

The burner flame still looks like it isn't a full flame.

What is the best way to clean the orifice ???
