Question about Daewoo DWC-121R Air Conditioner
Fan will run and the compressor will try to turn on (when on air conditioner setting), but then will turn off and the display will read E 1 and then fan will turn on again, over and over. Then if in the (fan only) setting it will read E 1 and turn on and off real fast, over and over, but the fan will run just long enough to turn off. The fan will only run about 2 seconds before shutting off in this setting (fan only) but turn right back on.
Thanks for the suggestion. I figured out the problem. The replacement fan motor I bought was general fan motor. it had 5 wires. Two of them went to the capacitor (this unit has combo capacitor, 3 leg). I followed the schematic diag on the motor and connected one leg to the C and the other leg to the FAN on capacitor. what was happening, the start winding was working against the run winding in the motor. Once I switch the wires in the capacitor, fan ran at full speed. thanks again for your reply.

This is a single speed permanent split capacitor motor for the condenser. One of the capacitor wires shows infinite resistance to hot and netral. The motor needs to be replaced.

SOURCE: Compressor Fan stop working
Do you have a meter? Either the fan is bad or the capacitor is bad. Ohm out the fan and then the capacitor. Be sure you take the disconnect out of the electrical box on the side of the house and or trip the breaker off. The capacitor is a dual run one side operates the compressor and one side operates the fan. I would really bet on the capacitor being bad. Have seen that a lot in my experience. Be sure to make note of the wiring of the capacitor before you take it out to check and if you are not sure how to check it take it to the parts house and they can check it.

The fan motor is getting hot and going off on the internal overload in the motor.
This is caused by either a low voltage, a bad capacitor, or tight or dry bearings in the motor.
To check the bearings turn the power off to the unit, then spin the fan blade if it spins freely then the bearings are ok.
To check the capacitor you will need some kind of tester or you can buy a capacitor and replace it, that's what a lot of people do. They usually don't cost very much.
To check the voltage you will need a voltmeter and measure the volts at the unit.
