Question about Heating & Cooling
The Operation and Timer lights are flashing sinultaneously we have tried all the things sugested in the operators manual but they are still flashing, and of course it has to play up now when we are heading into 39 degree heat.
I you already tried the power supply reset in the unit ("off" and "on" the supply) may be there something wrong with your thermistor, out of range thermistor can cause error display (flashing LED).Or running the unit with under charge refrigerant is also one of the cause. If the unit operates but no cool at all then that is the cause of error display. Please call a qualified technician to check your unit.

Turn off mains power at the breaker.
if you have an isolator at the indoor and out door unit, switch these on.
turn the power back on at the breaker.
