SymptomCheckDefectRemedy
Neither fan motor nor compressor workCheck power supply or plug, and measure voltage
  1. Fuse broken or contact defective
  2. Plug disconnected
  3. Plug connected but defective
  1. If fuse and switch are normal, check mains
  2. Connect properly
  3. Change plug
Fan motor does not operate
  1. Fan motor
  2. Motor lead
  1. Motor defective
  2. Fan touches, stops motor
  3. Inside wiring defective
  4. Wiring burnout
  1. Adjust motor position or blades
  2. Change or repair
  3. Change or repair
  4. Change or repair
Compressor does not operate
  1. No current runs (compressor circuit)
  1. Switch defective
  2. Compressor coil burnout
  3. Wiring disconnected or burnout
  1. Change switch
  2. Change compressor
  3. Change compressor wiring
  1. Current runs, below operating current capacitor normal
  1. Compressor burnout
  2. Switch contact defective
  3. No gas
  1. Change compressor
  2. Change compressor
  3. Fill gas
  1. Large current runs
  1. Compressor locked
  2. Compressor burnout
  3. Capacitor defective
  4. Starter contact defective
  1. Change compressor
  2. Change compressor
  3. Change capacitor
  4. Change starter switch
  1. Large current runs and compressor operates but stops immediately
  1. Compressor short
  2. Heat source near cooler
  1. Change compressor
  2. Remove heat source
Compressor does not start fullyCheck power source voltage
  1. Power source voltage too low
  2. Wires too thin
  1. Improve power source
  2. Use thick wires
Compressor starts but stops shortly
  1. Measure power supply voltage
  1. Voltage is low and over current runs. Overload relay operates
  2. Wires for power supply equipment too thin.
  1. Improve equipment voltage
  2. Change wires
  1. Check if air is delivered
  1. Thermostat operates. Fan does not.
  2. Thermostat operates, fan is loose.
  1. Change switch. Check electric circuit (fan)
  2. Tighten fan blade screw
  1. Check temperature of air sucked and heat exchanger temperature.
Very little differenceImprove ventilation
Electric shockInsulation resistance
  1. Over 10M Ohm on megger
  2. Below 10 M Ohm on megger
  1. Take proper earth
  2. Change defective or repair
