Hi Guys, I am new to this forum. I request an expert opinion cause I’ve not found anything relevant on the web search.
I have a Samsung double door fridge freezer refrigerator. Two weeks ago, it stopped cooling and clicking noise coming from the overload relay box plugged into the compressor. I took out the relay overload unit and opened it. I found thermistor disc in pieces. I bought a new unit along with new capacitor from parts store and fridge worked fine for 4 days.
It stopped cooling again and clicking noise. I changed it 2nd time which lasted 3 days and then 3rd time(lasted 2 days). I checked compressor readings. They seems to be ok(7, 10, 17). I started compressor with no relay(with overload plugged in) 4 or 5 times to use the food in the fridge. Every time I started the compressor without a relay , the overload switched off when it was cool enough. I don’t want to start it too many times resulting in compressor damage. I am suspicious that something else is faulty causing the thermistor disc in the relay unit to melt and fail. I also opened the relay when it failed 2nd and 3rd time and found the thermistor disc in pieces .But this failure is not happening with one start. . It is happening after around 20 start and stop cycles. How to check whether compressor is the problem?. The resistance readings seems to be ok and it is starting after replacing relay (thermister) and also without relay by momentary shorting of start and run windings with no problems. The water in the ice tray is freezing quickly in matter of couple of hours from room temperature which is bit unusual. Can this be a thermostat/evaporator fan problem? This fridge freezer is 10 years old, no digital controls, with manual disc controls for temperature both in freezer and fridge compartments. The Fridge is used at same location since brand new
Other observations: Fridge voltage stabilizer output voltage is 210 volts. Voltage going to compressor through relay unit is also 210 volts. Fan in the freezer unit is running and blowing cold air when compressor is started with or without relay.
Any help is highly appreciated.
Thank you very much,
