What went wrong???????

A couple yrs ago,
I installed 2-4" computer fans, with a snap switch that comes on at 85* and then turns off when the temp falls below the 85* mark,
in the back of the reefer to blow air up thru the heating coil section towards the roof vent,
to help reduce the heat in this area,
and make the reefer operate with less strain etc.

Everything worked perfectly when I used last yr, temps running 95-100+, for a couple of days.

This yr for the last week or so, the temps have been 90*+ to 105*, so far, direct sun contact on the side that contains the reefer.

I connected the manual stitch and the fans were doing as they supposed to. The better half makes the remark that the reef inside temp is/was getting warm??

I check it out and sure enough the reefer section is warm and the top freezer section is starting to thaw out. ??

I am thinking that the reefer blew up or is having a major melt down etc.

I disconnect the fans, while checking everything and going over every thing possible.
All systems are a go, Houston......

The total time spent checking and reading the OEM manual etc, was about 2 hrs, the wife walks by and states, the reefer is getting cold again, HUH???

What happened??
Did the 2 fans cause this problem, as it appears so?
TOO much air flow up thru the coil?

Any suggestions and or Ideas?

  • I run a small 120 volt fan all the time blowing up from the bottom of the coils all the time during spring, summer and early fall. It has real hot for the 2 Norcold fans to come on.
    If your fridge is a No Cold 1200 series, it may just have been going thru the defrost cycle. Our does this about ever 48 hours.
