No ac on. Thermoking apu fan cuts on and off it a 2022

If your Thermoking APU fan is cutting on and off, it could be due to a variety of reasons, such as:

Temperature settings: The APU may be set to turn the fan on and off based on temperature settings, so it could be turning on and off as it reaches the desired temperature.
Sensor issues: The temperature sensor or thermostat may be malfunctioning, causing the APU to turn the fan on and off incorrectly.
Electrical issues: There may be an issue with the electrical connection between the APU and the fan, causing it to turn on and off intermittently.
Mechanical issues: There may be a problem with the fan motor or the fan blades themselves, causing the fan to turn on and off erratically.

My carrier apu starts fine, on low ac it will stay running but the display goes to check apu engine. On high ac it will run for a few minutes and kill the engine. Could it just be a fuel filter issue?

Hi, I do not think a fuel filter will fix this problem. You may need to take this unit in for service. If the fuel filter was to blame. The engine would die at both fan speeds. More than likely The APU controller has identified a fault and shut the system down. I feel that the A/C high function is directly related to the engine shut down. Driving down the road (vibrations) can knock things loose, wiring can get damaged or its just wear and tear. You can remove the covers and visually inspect the connections. Look and see if anything looks loose, broken or over heated. You can also inspect the HVAV blower motor and speed resister. Specifically the wiring at the connector. Over heated wiring can melt and cause a short that can affect system operations. Please start here and write back. Good Luck.

It is possible that your starter motor is stuck. First of all you can place your vehicle in the 2nd gear and push to disengage the starter if it had the bendex stuck. there after try to start. If not you will need to remove the starter motor. carefully do remove and place it on a table . clean off all dirt, then open the motor carefully. you can even test the motor with a heavy power cord and the battery but please be very careful to hold or use a good vice grip to hold since the intial torque can make it slip from your hand. thereafter check the brushes and the bush / bearings. if damaged or wobbly change / replace. Now you can reset the starter motor and test.
I am sure it will work. Good day
