      [Webinar] Appliantology Workshop   11/09/2017

      Information is the name of the game in the appliance repair trade today. Appliantology is a powerful information tool for the professional appliance repair technician. But just like with any of the more capable tools in your tool bag, many of the more powerful features are hidden from you unless you "read the manual." Ugh! Who wants to do that? Well, this is one time when you don't have to! In this webinar, Team Samurai will personally walk you through the site and show you many of the useful and powerful features that even long-time users probably never knew existed.

GE Cafe fridge running / not cooling - CFCP1NIXASS

Recommended Posts

STVO

Hi, I've got a 7 year old GE Cafe series refrigerator that has become a headache and a potential money pit.  It's currently running with lights on, fan blowing, and power running from the mothaboard.  However, the compressor is not kicking on.  I've viewed all the great videos and posts on the possible issue, but, still can't identify the culprit.  Two local appliance technicians also took a stab at the repair, yet, only speculated it to be the compressor.  Here is what has been tried: run several full diagnostic tests, replaced inverter twice, and plugged in a new mothaboard. Diagnostic tests recorded: 8.4 volts from j15 wire pins and inverter while running; 122 volts from wall at inverter; equal 6.6 ohms at three compressor windings.  

Before making the leap to change out the compressor, I was hopeful there was another test to prove the compressor is locked-up?  

One other thing, when I plug in the fridge, I can hear a very light high pitched beep.  It sounds like an attempt by the inverter to start the compressor. This sound will stop and reoccur again minutes later.

Any insight is greatly appreciated.  Thanks.

You've already replaced the inverter (twice) and the mobo. Nothing else left but the compressor.

You're hearing the inverter attempting to run the compressor. But the compressor is mechanically locked up (bad bearing, whatever) so the inverter's internal overload protection is kicking in and cutting power to the compressor and attempting to re-start it a few minutes later.

Thanks for the advice.  I called GE and shared my frustration.  They offered to supply the parts at 50% off and send a GE technician.

Update:  A GE Technician came out and replaced the compressor, mothaboard, and inverter.  The fridge is running again and cooling slowly.  However, after 48 hours, the freezer is only down to 17 degrees, fridge at 37.  Is it typical to take this long to cool (assuming it will get to 0 at some point)?

Thanks, Steve

This is the baseline indicator of sealed system health. A freezer should be able to achieve and maintain 0F. 48 hours is plenty long enough for this happen. 

At this point, three questions:

1. How are you measuring the freezer temperature? And please do not say "I read it on the display" because that is not an independent measurement!

2. Is the condenser fan (the one by the compressor) running?

3. Is the condenser clean?

Culprit found.  After unplugging the fridge for 20 minutes I powered it back up, inspecting the compressor and fan.  Both kicked on and as the compressor started to heat up, I began to hear a clicking come from the fan.  Originally, I thought this was just the noise of the new compressor, however, as the compartment heated further, the clicking became louder and, ultimately, stopped the fan from spinning.  The issue was the plastic fan housing had been melted by the technician's torch when soldering in the new compressor.  Once, I trimmed back the warped housing, the fan spinned freely and the temps in the freezer and fridge went to normal within a couple hours.  

Thanks for your help.  My wife loves me again.
