What to do if my Electra Heat Pump refrigeration system does not function correctly?
If the refrigeration system of your Electra Heat Pump isn't functioning correctly, check for leaks or restrictions using an ammeter, pressure gauge, or surface thermometer. Repair the refrigeration system and charge refrigerant if necessary.
What should I check if the indoor fan of my Electra DNC Heat Pump isn't working correctly?
If the indoor fan of your Electra Heat Pump isn't functioning 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 should I check if the outdoor fan of my Electra Heat Pump isn't working correctly?
If the outdoor fan of your Electra Heat Pump isn't functioning correctly, check the voltage between the outdoor fan terminals on the main P.C.B. If there is no voltage replace main P.C.B. If there is voltage between outdoor fan terminals on the outdoor unit replace capacitor or motor. Check and repair electrical wiring between indoor and outdoor units.
What to do if the operation indicator (green led) on the Electra DNC central control display panel does not light up?
If the operation indicator (green LED) on your Electra Heat Pump's central control display panel isn't lighting up, the remote control batteries may be discharged. Replace the batteries of the remote control.
What to check if the operation indicator (green led) does not light up when starting my Electra DNC from the unit?
If the operation indicator (green LED) does not light up when starting your Electra Heat Pump from the unit, check the main P.C.B and display P.C.B. Replace P.C.B if necessary.
What to do if the stand-by indicator (red led) on the Electra Heat Pump central control display panel doesn’t light up?
If the stand-by indicator (red LED) on your Electra Heat Pump's central control display panel doesn’t light up, it indicates there is no correct voltage between the line and neutral terminals on the main P.C.B. If the voltage is low, repair the power supply. If there is no voltage, repair the general wiring. If there is correct voltage replace main or display P.C.B’S.
