GOT A GE TOP-FREEZER FRIG LAST MONTH (MANUFACTURED IN 2004). EVAP FAN WASN'TCOMING ON VERY OFTEN. CONTINUITY TEST WAS NORMAL FOR CONTROL TEMP (PART 300)& CONTROL DEFROST (DEFROST TIMER, PART 648) IN THE REFRIGERATOR SECTION.
I UNPLUGGED EVAP FAN IN BACK OF FREEZER & AFTER I PLUGGED IT BACK IN& MOVED WIRE IT A BIT, I SAW A FLASH, LIKE A WIRE SHORTED WHERE IT PLUGSIN. EVAP FAN DOESN'T RUN NOW.
WHAT NEXT? ASSUME I NEED TO TEST THE EVAP FAN MOTOR (PART 610) & DEFROSTTHERMOSTAT (PART 620)? IS A CONTINUITY TEST USEFUL DIAGNOSIS ON THE EVAP FANMOTOR IF I UNPLUG FRIG & TAKE EVAP FAN MOTOR OUT OF THE FREEZER? CAN'TFIGURE OUT HOW TO TEST THE DEFROST THERMOSTAT---CAN'T SEE WHERE WIRE GOES ORHOW IT IS ATTACHED NEAR THE METAL FINS. I SAW AN IMAGE ONLINE OF WHAT A GOOD& BAD DEFROST THERMOSTAT LOOKED LIKE BUT THE DIFFERENCE WAS'T CLEAR. WHATIS THE DEFROST THERMOSTAT SUPPOSED TO LOOK LIKE?
WHAT'S THE LIKELIHOOD THAT ONLY THE EVAPORATOR FAN MOTOR NEEDS REPLACING ONTHIS FRIG?
THANKS!
HERE ARE SOME SAMPLE TEMPERATURES AT TEMP SETTING 2: FREEZER: -31 & FRIDGE 38 ABOUT 6.5 HRS FROM LAST DEFROST CYCLE; FREEZER 9 & FRIDGE 36 WHILE DEFROST CYCLE WAS FINISHING; FREEZER -13 & FRIG 37 JUST AFTER DEFROST CYCLE FINISHED

[FONT="]i tested a 2ns evap fan from same model frig & the motor just got hot in the back but fan did not run. i removed it & put my 1st evap fan in & it ran but i noticed it was not seated correctly (rubber washer on backside had pushed thru) so i reinstalled it & fan did not run. then i unplugged frig without turning it off & plugged it back in about a minute later & the 1st evap fan was running. the 1st evap fan motor did not get hot on the backside when it was not running. evap fan running now has a growling sound at times---is this from how fan is seated or is it the motor?
i know how to test for continuity with multitester but not sure how to test for ohms---is the fridg plugged in for this test? [/FONT]
