When i turn system on for heat, heat blows for a couple minutes then cool air starts coming out of the system
SOURCE: amana ptec unit built into the wall
SOUNDS LIKE YOUR HEAT STRIP IS NOT COMING ON THERE COULD BE A NUMBER OF THINGS TO CAUSE THIS,BAD RELAY ON THE BOARD BAD HIGH HEAT LIMIT,BAD T-STAT
SOURCE: 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

On the heating element [behind the coil, (the springy thing)], at the top end of the element, there is a little thermistor I think it is called. You will have to remove the fan shroud. With the power off, check for continuity if you have a multimeter. If that is the problem (no continuity), you can pick one up at al local heating supply. Just have it soldered back in and reconnect. If the thermistor 's continuity is okay, remove the main board under the control knobs. I have seen these boards burn in the back where the relays are soldered on. If you're really good with a solder you can try to re-solder it. If not, it's about as cheap to buy a new unit as it is to buy the board. Good luck.
SOURCE: no cool air. blowing warm air
is breaker for condenser tripped---has it been running before -----is fan on outdoor ubnit running?
