Question about Freezers
I purchased a Gibson upright freezer model FV10M2WXFD it runds all the time. We replaced the thermostat and it is still not getting cold enough. All shelves get frost except for the one that has the thermostat on it. Any other options on what could be wrong? Thanks
This one sounds like the defrost timer is not working and you are not getting a defrost cycle every 6-8 hours (or when needed). Another issue could be that air (moisture) is getting in from a leaky door seal, etc. and causing the freeze up. If you have a sealed system problem where the cooling coils are not uniformly frosted up then the defrost thermostat will not "know" there is an ice condition and therefore not go into defrost mode (same issue if the defrost t-stat is bad). After you have ALL the ice out of the unit it would be a good idea to take the interior rear cover off so you can view the coils. Start the freezer back up and watch over the next 1/2 hour or so to see that the entire coil is frosting up uniformly. If it isn't you may have a plugged system, a leak causing low refrigerant, etc. If over time the coils look uniformly frosted up you may have a defective defrost heating element itself (no heat, no defrost sort of thing). The defrost elements can be checked with a multimeter for continuity if you know how to do that sort of thing. It's hard to know a person's ability by these forums or if they can tackle certain test procedures.

Three things could be the problem. Most likely would be the defrost thermostat which clips onto the evaporator behind the panel in the freezer. 2nd would be the timer or control board (will have one or the other). 3rd would be a bad defrost heater. Alot of times the def. therm. will show obvious sign of being bad by the cap on top popped open. You can check resistance on the heater. Any resistance at all on the heater means it is good. If it has a standard timer turn it clockwise until it clicks. This is putting it into defrost. If the heater comes on the timer is bad. If it has a control board you would unplug the unit then unplug the power supply to the board and jump line 1 to the wire going to the heater. While unplugged from the board and jumped, plug the freezer back in. If the heater comes on then the board is bad. If you are not sure how to test replace the def. thermostat, which is the cheapest part and see what happens. Note: When conducting the test for the timer or board the def. therm. must be freezing so don't defrost first! Hope this helps.

Sounds like the system is low on freon. The other common problem is a dirty condenser. Insure the condenser is clean, if it is. You will need to charge the system with freon. Which only a qualified refrigeration tech should do.

check your door seal, by closing the door on a strip of newspaper all round the seal. this fault is usually air getting inside the freezer, it rises to the top making thick ice or snow.
