Samsung Refrigerator Error Code 66C
Door handle heater error
Door handle heater error — resistance between Main PCB CN51 pins 1 and 2 should be 135 ohm ±7%; 0 ohm indicates heater short, infinity indicates open wire.
First step from the service manual
1
Separate Main PCB CN51 wire from PCB; measure resistance between CN51 pins 1 and 2.
The complete diagnostic procedure includes additional test steps, resistance specifications, wiring diagram references, and component test points.

Door handle heater error — resistance between
From Service Manual 105687, p.19:
1.Separate Main PCB CN51 wire from PCB; measure resistance between CN51 pins 1 and 2.
2.Measure door lock assembly resistance across the PTC terminals. Expected: ~200 ohms cold, rising sharply once energized.
3.Inspect strike and latch alignment. A warped door or misaligned strike prevents the switch stack from closing in the correct sequence.
Part DC34-00024B
