Once I changed the fans on my fridge (RF32FMQDBSR) the freezer seemed to stop working. I checked both compressors and both worked well so If someone could tell me why my freezer isn't working I would greatly appreciate it. Thank you.

If the freezer is not working on your Samsung RF32FMQDBSR refrigerator after changing the fans, possible reasons include:

1. Compressor not running – Check if the compressor is operating. If not, use the Self-Diagnosis function and ensure the compressor receives power.

2. Fan power supply issue – Verify that the voltage between Main PCB and fan connectors (CN76 #2, #3, #4) is about DC 8–12V. If not, the fan may not work normally.

3. Door switches not closed – Ensure all door switches (freezer, fridge, and door) are closed. If open, fans may not operate.

4. Faulty door switch connector – If the door alarm sounds, inspect and repair the door switch connector.

5. Delay after startup – After opening the door or in high ambient temperature, the fan may delay activation by about one minute. This is normal.

Check these points to identify the issue.

If the freezer on your Samsung RF32FMQDBSR refrigerator is not working after changing the fans, possible reasons include:

1. Compressor not running – Check if the compressor is operating. If not, it may be a power or control issue.
2. Improper fan voltage – Verify that the voltage between the Main PCB and the fan connectors (CN76 pins) is about DC 8–12V. If not, there could be a PCB or wiring issue.
3. Door switches not closed – Ensure all door switches are closed. If a door switch is open, the system may not operate correctly.
4. Misleading fan behavior – The R-Fan may delay operation by one minute after opening the door or in high ambient temperatures. This is normal and not a fault.
5. Faulty door switch connector – If there's a door alarm or incorrect voltage on CN76 #5, the door switch connector may need repair.

Use the Self-Diagnosis function to identify defects before turning off the unit.

Why is one side of my freezer defrosting

1 comments:

Mr. Anderson

April 13, 2025

One side of your Samsung RF32FMQDBSR/AA freezer may be defrosting due to a cooling defect caused by excessive frost buildup. This can happen if components like the defrost sensor, temperature fuse, bimetal, or heater are faulty or if there is a problem with the fan or wiring. You should check for:

- Compressor operation
- Refrigerant leakage
- Functioning of the R sensor, R defrost sensor, and R fan
- Voltage at the defrosting sensor
- Open circuits in the fuse, bimetal, or heater
- Relay or PBA (Power Board Assembly) issues

Also, ensure the freezer door was not left open, which can raise temperature and cause defrosting.
