Heat exchangers for rejecting heat to air are built into the outside walls. This is normal. Just make sure you have enough clearance for free air circulation around it.
Step by step look for the obvious such as; is the condenser clean on the unit outside the box, is the condenser fan motor running, is the coil inside iced up. These are common problems with freezers.
If the coil is frosted over the problem may be related to the defrost timer. Rotate the timer as per the arrows to the defrost position to defrost. This should cause the coil to defrost. If this does defrost the coil replace the timer.
If the condenser fan motor does not rotate with the compressor running, rotate the fan blade manually, if it is the least bit tight the bearings may be dry or gummed up, oil the motor with non-detergent oil SAE-20.
stopped up drain in the freezer remove back freezer panel and
unthaw the drain pan and the tube, the tube connects to the bottom of the metal pan, you will see a hole about the size of a dime direct the heat from the hair dryer at this hole it may take 20 min, to thaw
pour some water down the hole if it is clear of the ice the water will run to the drain pan at the bottom of the ref
if it does not keep thawing until it does
If condenser is clean, and everything seems to be working fine, most likely You will have a leak of freon(very slow usually) and 90% of the chance You will need to get quote to replace evaporator coils. Watch this video, might help to troubleshoot. Hope that helps.
They are usually mounted on the front panel of the evaporator or mounted on the wall behind the evaporator.There is a possibility that the temp. control is at the condenser,and the sensing bulb was slipped thru the wall.Look for the bulb at the back of the evaporator and follow the cap tube.
Yes if the evaporator drain is blocked or not attached correctly it causes the humidity to remain in the refridgerator. Just opening the door will cause the warm are to enter and cause the symtoms of rain if the water is not taken out the drain properly.Hope this helps JT
Is the compressor running? How about the fan motor? Chck. those items first and when there be sure coil is clean. Now coil is clean, fan and compresor are running, then you may have leak on the system. Quik test, unplug frige from wall and plug it back after a few second, if compressor runs, you have a leak.
