i have a carrier ac running with r22,
when on cooling suction is 58psi and machine runs perfectly well all day,
when on heating the machine runs correctly for approx 10 mins then... fan cuts out, discharge pressure drops from 270 to approx 240 psi and suction drops to approx 35 psi. Obviously the exterior heat exchanger starts to freeze
i have evacuated system and recharged and i am thinking that my next step would be to link the fan in to run full time in order for external coil to work better.
Am i missing something obvious?
is it correct to try linking fan as next step?
thanks for your assistance in advance :)
