I’ve got this job, the guy can’t decide quite what the symptoms are. He started by reporting that the fridge was not getting cold and the alarm was going off. Then the fridge was too cold. Any way to cut a long story short he moved house about 3 weeks ago and it was working fine for 3 weeks so he cancelled the job. But now he has rung up and told me that the alarm is going off intermittently but freezer is showing -18 and fridge about 3. Im thinking defrost heater or pcb. Anyone have any other suggestions before I go there? Cheers in advance DJ
