Why is my Electra DELTA 18ST Air Conditioner not cooling or heating, and only the indoor fan is working?
If your Electra Air Conditioner isn't cooling or heating, and only the indoor fan is working, the outdoor fan motor may be faulty, or another issue may have caused the compressor overload protection to activate. Try removing any obstructions blocking the outdoor fan. If that doesn't work, the P.C.B. may need replacement.
Why is my Electra DELTA 18ST blowing air but not cooling or heating?
If your Electra Air Conditioner is not cooling or heating, but the indoor fans are working, it could be due to the overload safety device on the compressor being cut out because of low voltage or high temperature. Check for proper voltage. Switch off the power and try again after one hour. If the problem persists, consider replacing the compressor capacitor or the compressor itself.
How to troubleshoot an Electra Air Conditioner when the outdoor fan is not working?
If your Electra Air Conditioner's outdoor fan isn't functioning correctly, 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. You should also check and repair the electrical wiring between the indoor and outdoor units.
How to fix Electra Air Conditioner when the indoor fan is not working correctly?
If the indoor fan in 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 the Electra Air Conditioner compressor does not start up?
If your Electra Air Conditioner compressor isn't starting, begin by checking the voltage on the compressor terminals on the outdoor unit. If there's no voltage, repair the electrical wiring between the indoor and outdoor units. If the voltage is low, repair the power supply. If the voltage is correct, replace the capacitor or the compressor.
Why is my Electra Air Conditioner in heat mode but operating in cooling?
If your Electra Air Conditioner is in heat mode but operating in cooling, the RV coil may be faulty, so replace the RV coil. If the RV coil is okay, the valve may be stuck in position, so replace the reversing valve.
Why is only the indoor fan and compressor working on my Electra Air Conditioner?
If your Electra Air Conditioner only has the indoor fan and compressor working, it's likely that the outdoor fan is blocked. Remove any obstructions to allow it to function correctly.
Why is there no air supply from the indoor unit of my Electra Air Conditioner, even though the compressor is running?
If your Electra Air Conditioner's indoor fan isn't providing enough air, and the compressor is running, the indoor fan motor might be blocked or turning slowly. Check the voltage and repair the wiring if necessary. Also, check if the fan wheel is tight enough on the motor shaft and tighten it if necessary.
Why is only the indoor fan working on my Electra DELTA 18ST Air Conditioner?
If your Electra Air Conditioner is only running the indoor fan, the run capacitor of the outdoor fan motor may be faulty, so replace the capacitor. Alternatively, the windings of the outdoor fan may be shorted, so replace the motor.
Why is the operation indicator on my Electra DELTA 18ST Air Conditioner not lighting up?
If the operation indicator (green LED) on the central control display panel of your Electra Air Conditioner does not light up, the remote control batteries are discharged. Replace the batteries of the remote control.
