Why is my Electra WMZ 7 Air Conditioner not cooling or heating, and only the indoor fan works?
If your Electra Air Conditioner's indoor fan is running but there's no cooling or heating, the outdoor fan motor may be faulty, or another issue might have triggered the compressor overload protection. Try removing any obstructions blocking the outdoor fan. If that doesn't work, the P.C.B. may need replacement.
What to do if my Electra WMZ 7 is not cooling or heating, but the indoor fans are working?
If your Electra Air Conditioner's indoor fans are working, but there is no cooling or heating, the overload safety device on the compressor may have cut out due to low voltage or high temperature, the compressor run capacitor could be faulty, or the compressor windings may be shorted. Check for proper voltage, switch off the power, and try again after one hour. You may also need to replace the compressor capacitor or the compressor.
What to do if my Electra Air Conditioner is in heat mode but operating in cooling?
If your Electra Air Conditioner is set to heat mode but is operating in cooling, the RV coil may be faulty, or the valve may be stuck. Replace the RV coil or the reversing valve.
Why is my Electra Air Conditioner outdoor fan not working correctly?
If the outdoor fan on your Electra Air Conditioner isn't functioning properly, check the voltage between the outdoor fan terminals on the main P.C.B. If there's no voltage, replace the main P.C.B. If there is voltage, replace the capacitor or motor. Also, check and repair the electrical wiring between the indoor and outdoor units.
Why is my Electra Air Conditioner only running the indoor fan?
If your Electra Air Conditioner is only running the indoor fan, the run capacitor of the outdoor fan motor may be faulty, or the windings of the outdoor fan may be shorted. Replace the capacitor or the motor.
Why is my Electra WMZ 7 indoor fan not functioning correctly?
If the indoor fan of your Electra Air Conditioner isn't working correctly, check the voltage between the indoor fan terminals on the main P.C.B. If there is voltage, replace the capacitor or motor.
What to do if my Electra Air Conditioner compressor does not start up?
If the compressor on your Electra air conditioner isn't starting, begin by checking the voltage at the compressor terminals on the outdoor unit using an ammeter. If there's no voltage, the main P.C.B. may need to be replaced. If the voltage is low, repair the power supply. If the voltage is correct, consider replacing the capacitor or the compressor itself. If there is no voltage, repair electrical wiring between indoor and outdoor units.
What to do if water accumulates and overflows from my Electra WMZ 7 Air Conditioner indoor unit?
If water is accumulating and overflowing from the indoor unit of your Electra Air Conditioner, the drain tube or spout of the drain pan is likely clogged. Disassemble the plastic drain tube from the spout of the indoor unit drain pan to clear the blockage.
Why is my Electra WMZ 7 Air Conditioner only running the indoor fan and compressor?
If your Electra Air Conditioner is only running the indoor fan and compressor, the outdoor fan may be blocked. Remove any obstructions.
What to do if my Electra WMZ 7 has freeze-up of outdoor coil in heating mode?
If you notice freeze-up of the outdoor coil in heating mode on your Electra Air Conditioner, resulting in a poor heating effect while the indoor fan operates, the outdoor thermistor could be faulty, the control cable might be damaged, the outdoor temperature may be below design conditions, or the outdoor unit air outlet might be blocked. Replace the thermistor or repair the control cable. If the outdoor temperature is too low, shut the unit off as it cannot work properly. Also, ensure there are no obstructions blocking the outdoor unit air outlet.
