[SIZE=3]I have a Frigidaire side by side unit model # FRS26R4AQ4, 6 years old.[/SIZE]
[SIZE=3] [/SIZE]
[SIZE=3]It will run fine for 3 or 4 days, and then it will thaw for 12 to 18 hours before coming back on (during this time the compressor would make a very low humming sound off and on). Then it will start the cycle again. I did notice this last time, some ice on the back of the freezer compartment. [/SIZE]

[SIZE=3]Does this mean my defrost heater is out, causing a thaw without the heat from the element which is why it take 12 to 18 hours or is the defrost thermostat faulty?[/SIZE]
[SIZE=3] [/SIZE]
[SIZE=3]I have replaced the control box which consists of freezer and refrigerator thermostats, circuit board, damper and motor. I have also replaced the compressor capacitor thinking it was bad (but was not).[/SIZE]

[SIZE=3]Please help……I’m going insane.[/SIZE]
