We have an eight year old Frigidaire 7000 BTU portable that has been running in a 40 sq-ft pantry during the hot desert summers. Exhaust is going out the window. Unit is running on a heavy duty 6' extension cord. The top humidity outlet has a hose running out of it to a can, the bottom port was plugged.

Last few months the unit has occasionally made a growling noise and stopped cooling. Shutting it off for a while usually solved the problem. Due to its location at the back of the pantry on a rack, we were not able to check the coils whenever this happened. There was adequate space (8") between the back of the unit and the rear wall.

New problem is that after unplugging it overnight, when plugging the cord back into the wall socket, the unit automatically turns on. At that point the unit is unresponsive to either on or off commands on the remote or the main power button and continues running until unplugged. Sometimes after setting overnight it will work okay in the morning, definitely a sporadic problem.

Upon examination there was some water in the plugged lower tray which we drained out (maybe 1/4 cup).

Any suggestions appreciated.

The unit will obviously need to actually inspected to determine where the sound is coming from and why. It might be from the fan motor bearing or maybe due to a frost build up inside the unit.

The ON/OFF functions are switched by the unit's electronic control. If it is not switching at all, that control is likely defective and needs to be replaced. Unfortunately a new electronic looks to be discontinued. I did find a couple of used ones available at the following link.

Thanks for the reply Dan. It's definitely not the bearing, the frost idea is a good possibility. I'll watch for that.

The electronic control somehow seems to reset after leaving the unit off and unplugged for 12+ hours. I also see from the manual that it can give error codes on its digital display, so that will be something to look for.
Thanks again,
Jim
