Amana PTH153B50AM PTAC where the heat runs intermittently.

i'm not familiar with your specific unit but ..sounds like an electronic gas value has gone bad or has a bad connection when that happened to my friend it wasn't that expensive to have it fixed .. BYW it acted like this for a while then stopped working completely

Error code C7..amana ptac 2012 r410a runs compressor 5-10 min then will not run only fan. freon level is good. reset and compressor will run again then only fan again..cleaned

That means evaporator coil is too cold, possibly iced, chech filters, fan speed, airflow, capillary tube

You said in another post that the error was c7. That means evaporator freeze. Too cold. That could be lack of air flow, bad sensor, ice on the coils.

Have Ptac units that work fine one minute and 2 hours later just blow warm air.. some that also freeze up the front coils

I think your PTAC is under charge, if the air filter is clean and the evaporator is also clean together with the blower. Check the freon charge and refill if suction pressure is below 50psi and discharge is below 190 psi.

I have an Amana ptac hotel type thru the wall unit. The unit won't turn on - it's plugged in. The gfi button is popped out. There is power to the wall plug. Any ideas?

Hi,
If you reset the GFCI button and then when you go to turn it on the button pops again, then you have a short inside the units probably in the fan motor or the compressor..

AMANA PTH153B35AE PTAC Temp drop??

PTAC temp drop should be 20 to 25 degrees across the coil. They never put a service tap on these units. I sell Amana PTACs. You may be alittle low on gas. Check your air TD and that will tell you. The compressor may be overheating due to lack of cool gas to cool the comp. May need a service tech but get a free estimate first. Rus

Amana PTAC

Sounds like if this is a heat pump, maybe it tripped out on high pressure. Maybe just unplugging the system may reset the control boards. This maybe due to a dirty filter or dirty evaporator coil.
