When I turn the unit on, after a delay, the fan in the attic/blower unit comes on, after about 1 minute, the transformer smokes. The internet said to check for wires that are shorted. I did a resitance check on all wires after disconnecting them from the terminal blocks and they all checked out good. I had a service tech come out, I live in the country, 45 miles away from the closest, 90 miles round trip. All they wanted to do after replacing the transformer and it burned out,was to replace the entire unit quoted $2,500, I am trying to avoid this charge.., again the fan/blower works so I don't see why I need to replace that unit, maybe the compressor is bad, but the tech said that was not the problem, however, I never heard it come on. ideas please.. maybe something as simple as a capacitor or a switch?

Hi, not enough detail not enough detail. I have no idea where you are located, but if it is a gas heater/ Ac then maybe the attic space is so hot that the over temperature sensor is turning the unit on in an attempt to cool the system down. If however it is a refrigerant AC unit, I would suggest that the control circuit is faulty, maybe a sticking contact somewhere.
Do you have a heat pump? If so this is normal. You are probably used to a gas furnace. There are heat pumps that do have a delay though. Look on the circuit board in the air handler. There may be a set of pins that say 0-30-60-90 yours may be at 0. Also some digital T-stats offer that function for delay off to get the extra heat or cold from the system. Find out what the model number of the air handler and call the Goodman supplier in your area to see if you have these options. If you have a gas furnace and it's not delaying the blower there is definately something wrong.
That's a weird problem. I wonder if the outside compressor is drawing down the voltage in the breaker box enuff to keep the blower from starting up. If you're set to cool but the thermostat is NOT calling for the AC, can you manually turn the blower on fathfully? If so, I would check all wiring connections in the breaker box to make sure they are tight and free from tarnish or corrosion. You may even need to contact your power company and have a higher amperage line installed outside. Do your house lights blink noticably when the compressor kicks on?
While you're resolving this, you could start the blower manually and just leave it on. The compressor cycling on/off shouldn't stop the blower once it's running and it won't draw much current... couple bucks a month maybe.
THE BURNING SMELL IS NORMAL. BEFORE HEATING SEASON OPEN ALL DOORS AND TURN THE HEAT UP AND LET RUN TILL ALL DUST IS BURNT OFF.
IF BLOWER IS NOT COMMING ON NOW. THERE ARE 2 TIME DELAY RELAYS, AND ANOTHER RELAY FOR "FAN ONLY OPERATION". ALWAYS MAKE SURE THEY ARE NOT THE PROBLEM BEFORE REPLACING AN EXPENSIVE MOTOR.
