Re: Air conditioner line freezing up

Check to make sure the filter inside the air handler is clean and that no vents are closed or blocked by furnature or rugs. Check the air handler to see if the blower is operating. You could have a belt off, the door switch could be in the open position or something simple like that. If this checks out OK., you will need to have a technician check the charge

Model # m6p09s2a portable maytag air conditoner light keeps blinking at the unit where power button is located....unit will not turn on. the light just keeps blinking


I have the same model air conditioner, and had the same symptoms. As you've probably discovered, Fedders is the company that actually built it, and went of business. No one is supporting it any more.

However, you may be in luck. I fixed the problem by simply tipping the unit almost all the way over on its back (leave a little gap) and letting the water drain out of the hose and the filter. After that, it started right up.

Hope that works for you. Stay cool. :)

Compressor lines

If the large line returning to the compressor is frosting you don't have enough air circulation. Check air filters on inside unit.

My AC unit keeps freezing up on the copper lines going into the house from the outside unit. It also freezes up on the inside lines and the air is not cooling my home down.

Operate your air conditioner with the fan in the on position. But first turn the fan on, turn the temp up or shut the cooling off. Your coil is more than likely frozen over. At night when outside temperature drops the refrigerant pressure and temperature in the system also drops. This action can cause icing of the cooling coil, with the fan in automatic everything shuts down at the end of a cooling cycle. Thus no air movement to melt ice on previous cooling cycle.
