Our Fridge is out of warranty and I am looking for ways to diagnose it and fix it
After a storm we had knocked out the power, all of our appliances went out. When the power came back on all the appliances came back on except for the fridge. I can see that there is power to the unit as I have checked the outlet. Also the light on the ice maker selector inside the door goes on and off with the switch. However the water and ice dispenser panel on the door won’t come on. I have read that there are ways to reset the unit using the panel, but if the panel won’t come on, I can’t use it. I have removed the back cover off of the main panel and checked the fuse and connections and everything seems to be fine as far as I can tell. I am looking for other items and parts to check before I buy another main board. any help would be greatly appreciated. thank you
After a power failure some refrigerators will flash an error code and some turn the unit off. Your owner manual will tell you what combinations of buttons to push to turn it on. You might try unplugging it then plugging it for a minute, then plug back in. This resets the control board.
I would use a multimeter and just work down the power train to see where the break is. Start Relay The start relay works in conjunction with the start winding to start the compressor. If the start relay is defective, the compressor may sometimes fail to run or may not run at all. As a result, the refrigerator will not be cold enough. To determine if the start relay is defective, use a multimeter to test it for continuity between the run and start terminal sockets. If the start relay does not have continuity between the run and start terminal sockets, replace it. In addition, if the start relay has a burnt odor, replace it. https://www.repairclinic.com/PartDetail/… https://www.repairclinic.com/PartDetail/…
Hi @tfmc , Here’s a link to a page from the service manual that may be of some help Here’s also a link to a schematic for the fridge
Hi @Geoff Gordon, Here’s the schematic from the service manual, of the power supplies used in refrigerator that may help. It shows the location of the 15.5V DC, 12V DC and 5V DC power supply test points. Maybe a good place to start, considering that the panel is dead. Be safety aware when testing as there is lethal 115V AC as well near to where you will be testing.
