I replaced the thermostat 4 times in 6 months what's hapend? from a refrigirator true ts 49

SOURCE: True TS-49 Refrigerator freezing food

NEWER T-49 s DO NOT HAVE ANY DEFROST HEATER OR TIMER OR CUTOFF'S All solutions involving repairs on these items are bogus. The defrost occurs when the compressor shuts down normally. During this time,since the fan never stops, it should circulate above freezing air around the coils and a slow defrost may occur. It is a poor system at best, and does not work well if the compressor runs a lot. MY erratic cooling was fixed by removing the copper sleeve and cold control probe from the evaporator(cold coil on top) Polish up the copper tube and the probe, reinsert and bend the copper sleeve very slightly so that it fits snuggly into the evaporator. Mine was very loose and not making good contact with the metal evaporator, giving erratic control of temperature.. Good Luck!!

It sounds like you need a new fan motor. Is it the fan inside the refrigerator compartment or the very bottom of the unit? And what do you mean by not sealing? Let me know. I can order the parts for you.
