Central heat works fine, but a/c does not come on and the blower in the attic doesnt come on when switched to cool only for heat. Touch R & G wires together nothing happens. R & Y nothing happens....

Probably not in the wiring unless you did it yourself. Most likely it is the outside unit that is not coming on for any number of reasons. Call a tech to trace the problem.

Ac unit runs, inside blower shuts off after 2 mins, compressor continues to run, t-stat still calling for cool

My central AC unit decided to stop on the hottest day of the year. It would start and run normally for a few minutes and then the blower would shut off. After checking the breakers, thermostat and overflow shut off (did not have one) I saw something about a blower motor capacitor. This was easy to get to and replace and my last hope before waiting for someone to come fix it. The capacitor cost $4.04 with tax and had my AC working again. Needless to say I was beyond happy. I hope this can help others with a similar problem.

I have a Goodman GMH950904CXAC. Thermostat calls for heat. It comes on and runs fine for about 5 minutes, then the circulator blower shuts off, but burners and draft blower still run. After another 15...

4 flashes is an overheat situation most likely caused by the blower not blowing. The blower relay controls the blower function. It is part of the circuit board. I suspect a new board will take care of the problem if you don't find a lose wire or something simple.

My heater is not working. When the thermostat is placed in HEAT mode, it sounds like the blower is kicking on - but then it shuts down a minute later. I looked in the unit in the attic, and I can see that...

Yes. First go into the attic and look thru the the inspection hole in your furnace. It is a small hole with a glass cover you can look thru. Therer will be blinking light inside. The numrer of blinks tell you that what the problem is. Example three blinks means air switch open. Your problem could be ignitor,air switch or pikot. Get back to me asap and I will walk you thru this or call me. Rus

Blower never stops. AC outside jammed to stay on???

You need to call someone who truely knows what they're doing. From your decription, the person you had out should not be working on units. You have a problem most likely caused be the person that installed the new motor and these units are not designed to be worked on by the homeowner. There are hazards that could cause damage or injury.

Blower in attic & AC unit outside continuously run

Sorry to hear about your miss-fortune, you are right it is an wiring problem. Can you turn off the blower with the thermostat (cool-off-heat) or what happens when you switch the fan to (auto or on) When you say the outside unit is "rigged" is it mechanically being jammed or electrically? If its mechanically that should be removed (what a crappy thing to do) other wise it will run continuously as you may already know. That is what it sounds like, you should just be able to shut the entire system down by turning off the switch to the furnace. If it is electrically being held closed, he changed some of the wiring around in the attic unit, you better hope he was lazy and jammed a stick in the contactor in the outside unit or else you may need to learn more about HVAC wiring, none the less I would double check the thermostat wires going to the attic furnace there should be nomenclature on the unit or at least somewhat marked. This was probably disturbed when the new blower was installed, by the way that was your initial problem. Good luck and becarful

Air handler only blows air for 3-5 minutes before shut off & not cycling frequently

Sounds like it could be a very weak run capacitor on the blower motor. Run capacitors are sized specifically to the needs of the motor. When a run cap gets weak, the motor trys to compensate for it by drawing more power. More power draw = more heat in the motor, then the motor will overheat and shut off to protect itself. When the motor cools off it will automatically restart and run until it overheats again. Keep in mind that I am a technician that normally diagnoses equipment in a hands on manner. There are many practices and concepts that transcend all air conditioning systems but it is a constantly evolving industry. I live in south eastern WA and I don't see Amana units except as window units. It is possible to have something else causing this problem (faulty thermostat, failing thermal relay(if used), problem with electronic controls(if used)) there are a lot of potential variables
