Hi,
I have recently started noticing flickering noise from my refrigerator. It’s a 2 door refrigerator , GE 24.9 Cu. Ft. Capacity Side-By-Side Refrigerator with Dispenser.
Now the cooling in the refrigerator and regular compartment seems to be fine. I tried restarting the fridge from MCB and it is still making noise.
Opened the back panel and realized it is coming from the circuit area. Wearing rubber gloves I touched a point or two and could feel the vibration and was able to narrow down the source of sound in that area. But am clueless from there.
Here is a pic of back panel along with noise.
The relay on your control board is dropping out. It wither failing, unable to hold the voltage. Or, the voltage to the relay is dropping out, meaning another component that supplies voltage to this relay is failing. If the compressor feels really hot to touch, it could be the relay to the compressor and this “on and off” voltage at the compressor could damage it. To properly troubleshoot and diagnose this issue, id recommend scheduling a qualified technician to come and check it. The parts are expensive and without being at the unit with my test equipment, I would only be guessing. The inverter boards can generate over 250v even though it’s plugged into to a 110v outlet. UNPLUG IT BEFORE DOING ANYTHING. You can easily remove the board and look for burnt spots or swollen capacitors. Look for a board by the compressor. Inspect it too. Any signs of a burnt spot means it must be replaced or repaired. That’s the best I can do for not being in front o it.
Hi @vjsfbay , What is the model number of the fridge? Is sounds like a relay clicking on and off at intervals There are relays mounted on the pcb (black rectangular components with lots of writing on them) one of which may be operating and not holding . Place your finger on each one and check if you can feel if it keeps operating and releasing on one particular relay. Hopefully it is possible to find a schematic so it is known what the relay does.
