Bruce for Model Number GSL25JFPABS

I bought this side by side fridge from someone on Craigslist (big mistake). The first time I plugged it in, I waited a day both the fridge and freezer barely even got cool. Found out the evaporator fan was dead (removed the fan and applied 12v to it, no movement (I'm an electronics technician by trade). Motor wasn't siezed either, turned freely by hand. I replaced it and both fridge and freezer seemed to be at normal operating temps. I replaced the broken auger in the ice cube tray as well, it was broke when I bought it. I hooked up a water line and everything seemed to be great. Then I noticed the evaporator fan speeding up and slowing down (as if you were plugging it in, then unplugging it once a second). Very odd. And the light in the freezer would go on and off like it wasn't getting a good connection. I replaced the light socket. Then the defrost heater was open (freezer wasn't getting as cold as it used to be, found the evap coils frozen solid! Ohmed out the heater, it was open). I replaced the heater element. Now, when I'm making ice cubes, a few days later, the ice cubes are a solid mass, all clumped together and won't dispence anything cause it's such a big solid mass of ice. The solenoid that controls the crushed/cubed lever on the ice bucket sticks and won't actuate anymore. I replaced the solenoid. I also replaced every thermocouple in the unit, as it had the old rounded style thermocouples. I also replaced the defrost thermostat. If this thing was a horse I'd shoot it. I'm assuming, that there's only one part left to replace.. the main logic board. Would the main board cause all of these problems?!! Thanks.

Hello Bruce. Yes, it sounds like the main board will need to be replaced on the unit also.

Pam, If we had a better idea of where the clicking noise is located and a model number we could probably give you a better idea of the problem. But, in a lot of cases a loud clicking noise is usually the start relat attempting to start the compressor in the back of the refrigerator. With everything working OK and it cooling properly, it's a little hard to determine at this point.

Hello Tyler. This sounds like an issue with the sealed system. You will need to contact an HVAC tech to come out and look at the unit.

Rich, You will want to pull the rear wall of the freezer and check to make sure that the coils are not frozen over. If they are then this would be a defrost issue and you will want to check the temp sensor for resistance of 5K ohms at room temp. If it checks ok then test the defrost heater for continuity and if both check ok then the control board will be the issue.

Hello Stan. If the unit is cooling properly, then everything is ok. If it is not cooling properly, try cleaning the coils in the back of the unit and make sure the condenser fan is running good.

Hello Eddie. Make sure the freezer is between 0° and 5°. You need to check and see if there is power going to the water valve when the icemaker cycles. If so, replace the water valve on the unit. If not, or the icemaker does not cycle, you will need to replace the icemaker on the unit. Also, check and make sure the fill tube on the unit is not frozen and clogged. If so, replace the water valve and thaw out the fill tube. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Hello Jtigner. HI is an error for high temp. You will need to check and make sure the evap fan motor is running properly and the damper is opening to allow the air to come into the unit. If so, then check for a defrost issue with the unit.
