Re: tech manual
Hi Andy,
Thanks for reply. No actually it has frosted up evaporator. There is no defrost heater connected on Bigatti timer,so understood defrost is through stopping of compressor at certain time intervals with continued operation of the evaporator motors.
For the time being after a defrost is running fine but am metering performance.

Re: tech manual
yeah its off cycle, just test the timer operation, probe, fans, and air flow. not alot to go wrong really, common problem with these cases that i have noticed is the evap fans can quickly get water logged if the drain becomes blocked due to the close clearance from the base to fan.
