Hi,

 

This customer had two problems.

 

Temps were fluctuating up and down and intermittently there was a loud whirring sound in the freezer.

 

I replaced the computer and sensors and that seems to have handled the temps, but the loud sound is still going on in the freezer.

 

I have not heard it when I was there, but the tenant told the landlord it's still happening.

 

I'm suspecting the evap fan motor is being told to go into high speed and it can't handle it.

 

Changing the fan motor should handle that.

 

Any differing opinions??

 

Thanks,

Bruce

OR, could be the "good" Fan hitting an overly-frosted Freezer Evaporator

Reg is right. Whenever I hear the "moaning and howling wind" sound of the RPM whirring up and down I immediately think "air flow issue" and the 10942 board is trying to compensate because it can't stabilize the RPM feedback signal from that DC evap motor.

 

Check your coils for frost high up on the coil pack. You may have a weakened defrost heater that needs replaced.

the board tells the fan when to change speeds and it takes a minute or so for the speed to change. Rapidly changing speeds usually means a bad board. Since you have a new board installed, let's hope it's the fan hitting frost as Sensei Reg says or an out of balance fan blade.  If no frost or warped blade, you probably should change the fan motor asap before it damages the new board. If you still have the old board, check for burnt resistors under the j2 connector. If you see that, definitely change the fan motor regardless.
