My Amana bottom freezer / top refrigerator has started to work intermittently. The freezer is cold, but no cool air reaches the refrigerator. At first we thought that it needed to be defrosted (the freezer door had been left ajar overnight and a lot of ice had built up in it). Then the fridge started cooling again - but it turns out it's not working 1/2 the time. We had a repair man come, who ordered a new fan motor, but found that the new motor was not working. He thought they sent him a faulty motor, but when he checked it back in his shop, he found the motor worked, but stopped when he reduced the voltage. His diagnosis: we have a short somewhere in the fridge, impossible to find and fix. ?? Can you help?
No No No. The most likely reason that the evaporator fan is not running is that it probably uses the heater circuit for its neutral feed. I.E. In order for the fan to have 230v/115v it needs a zero voltage brought back through the defrost heater and defrost stat. I know this for a fact because I just did one today and have fallen for this scenario (ie bad fan motor) before. You need to check from ground(earth) to each side of the fan motor (which is easily accessible) and then across the fan motor windings. The chances are that you have zero voltage across the motor. The fan will also not run until the temperature of the evaporator coil has been brought below 0 'C (32'F) and this can take up to 20 mins (again speaking from experience). This is to prevent snow being produced after defrost. I would advise getting the engineer to come back if you have paid him money and do a proper job. Shorts in Amanas can happen but have not come across one yet. Hope this helps.
After melting ice (behind freezer rear cover inside freezer) using hair dryer can also wash bottom of fridge with spray of water (rather then vacuum), connect to electricity and let stand for 20 min. works great since. thanks
