When does cooling fan come on?

this is all you need to do sometimes once total de-iced try again after the defrost if the problem returns then either the defrost element is faulty or its not going into a dfrost cycle

if the thermostat is calling for cooling the fan will run 24-7

the issue is most likely not with the thermostat, set the temp down to 65 degrees and listen for a click at the thermostat (it may not make any sound). go outside where the condensor fan is and look to see if the fan is spinning. if it is then the thermostat is probably ok. If you still are not getting anycool air and just warm air pumping out you may need to have someonne come and check the coolant level in your system. It may just need a recharge, but if you have lost coolant there may be a leak in your system. Alll that being said, you may need a licensed professional to come out and check your system

Good day,
If the freezer is performing properly then in warm weather this is entirely normal. That is the condenser tubing and as it gets warmer, the inside gets cooler.

if freezer is close to zero, top to bottom, and fridge is warm(ing), then you likely have a defrost problem, you will notice an abundance of snow/frost on back wall of freezer. it could either be your heater, thermistor, defrost safety thermostat, or your defrost control/main cpu, depending on model. if either or both sides are warm at the top, and cold at bottom, then your freezer fan is out. again depending on your model, it may just be the fan, or a combination fan/main cpu board hope this helps

Check the thermostat, wich usualy causes such problems as fridge isn't cooling. And the fan itself only blows the cool breeze so it prevents from frost.

Best of luck

Start by replacing the coolant cap and thermostat, then replace the hi and low radiator fan relays,

sounds like a bad defrost thermostat, , unit not "self defrosting"

sounds like the unit is low on charge.you will need a pro to check it

check you paperwork , and manual. sounds like a compressor issue, which "should" be covered by 5 year manufacture warr. reason i say "should" is hte warr's all changed jan1/06. only one year form there . but check your manual itll have the warr info in it
