Question about Zanussi ZX55 / 4 Bottom Freezer Refrigerator
Seems like a regular problem on here, but my 2yo Zanussi Z55/4 is broken! The freezer compartment was working fine, but the fridge stopped - no air coming through the cool flow duct. When I open the freezer door, surprise surprise, the air starts flowing into the fridge??? Also, yesterday the freezer started warming up. I took the back panel off the freezer and the coils were totally iced up, so I let them defrost with the unit off for a while and the freezer is working again now. However, don't really want to spend £50+VAT call out if there is a solution to my problem that I can try? Please help!!!!
The defrost cycle is not happening like it should, that's what causes the block of ice (and poor air flow). If you have all that defrosted look at the defrost bi-metal, it usually is a small round disk with a couple wires coming out of it and it's clipped on the coils. When it's cold enough, it passes electricity to the heat elements, when it gets hot enough it "opens" and kills power to the heat elements. If that is bad (swollen cracked or bloated) and not passing electricity to the elements that's the problem. Another item would be the defrost timer itself, if it doesn't work (no clock motor turning) then it will never go into defrost. And the last and usually least expected failure would be the heat element themselves no working. Good job trouble shooting!

Superb advice - thanks! Have managed through a combination of warm salty water and patience to remove the block of ice, and the fridge is now working again! Longer term I think I will look into replacing the defrost timer when I have the money - will also check the bimetal but to be honest I'm bored with taking the back off for a few days! Thanks - were it not for your excellent advice on other similar problems I would never have been able to find the problem!
Starts and stops starts stops Freezer works but fridge is warm
