Frank Wiegand, Thanks for your info about the Nova Kool fridge, I wrote them at the email address you gave me and had a reply 20 minutes later. Now I'll have to find some time to check their suggestions and see what's going on. Thanks!

When I switch it on via the thermostat switch, the compressor and the fan both start running, then both switch off after about 3-4 seconds and stay off for about a minute. Then this cycle repeats automatically, as it tries to get running every minute.. There is no problem with voltage, no problem with dust or ice or anything else obvious. The unit is clean and dry and ice-free... and warm. Can you suggest what may be the problem with this unit? Fred Tug 44
