Kenmore 407.83086 Air Conditioner Error Codes

Error CodesPossible CausesSolutions
E5• Low Voltage Protection• Unplug for ten minutes and then turn on unit. If “E5" is still displayed call to arrange for product inspection and repair.
H8• The backup water tank is full• If the water tank is full the warning sign "H8” appears in the display. To restart operation of the unit, unplug from the electrical outlet and then remove the plug of the lower drain outlet to allow the water to drain. Use an appropriate collection pan. When the water has been completely re- moved, restart the unit. The unit can now be used as usual.
F1• Indoor ambient temperature sensor is mal- function• Unplug for ten minutes and then re- start unit. If "F1" continues to appear call to arrange for product inspection and repair.
F2• Indoor evaporator temperature sensor malfunction• Unplug for ten minutes and then re- start unit. If "F2" continues to appear call to arrange for product inspection and repair.
F4• Condenser temperature sensor malfunction• Unplug for ten minutes and then re- start unit. If "f-4" continues to appear call to arrange for product inspection and repair.

Kenmore 35132 Air Conditioner Error Codes

Error CodeCauseSolution
E1• Room temperature outside the function range:• Temporary error of start temperature. Please switch the unit off and start it again after approx. 30 minutes. If the error occurs continuously, the unit requires qualified inspection.
• Room temperature inside the function range:
E2• Temperature of the cooling agent lines too high or too low• Temporary error on measuring output temperature. Please switch the TRANSFORM unit off and start it again after approx. 30 minutes. If the error occurs continuously, the unit requires qualified inspection.
E3• Incorrect signal• This error message in the cooling function refers to too high ambient temperatures and in the heating function to too low ambient temperatures. This may also be a temporary error measurement between the start and output temperature. Please switch the unit off and start it again after approx. 30 minutes. If the error occurs continuously, the unit requires qualified inspection.
E4• Water tank full• If the water tank is full, the warning sign "E4" appears in the display. To restart operation of the unit, please remove the plug of the condensation water outlet to allow water to leak out. Please use an appropriate collection tank. When the water has been completely removed, please start the unit again. The unit can now be used as usual.
DF• De-icing mode• This procedure is completely normal and protects the system from icing and failure. The unit starts automatically after approx. 1 5 minutes again (depending on the function setting). This procedure repeats itself regularly.
