The interior light on fridge and freezer are flashing continuously. Front panel is showing upside down codes. Compressor is not starting. I changed door switch didn’t do nothing.
Can you please send me manual or put me in the right direction on what could be the problem?

Go through the diagnostics below this should get you any error codes. Once you get the error code we can further diagnose the issue. https://www.appliancevideo.com/?cat=&s=samsung+refrigerator+&post_type%5B%5D=post&post_type%5B%5D=premiumvideos&post_type%5B%5D=fromthefield&post_type%5B%5D=embdvideo See Samsung refrigerator videos

Self Diagnosis: Press the Pwr Freeze—Pwr
Cool buttons simultaneously for 8-12 seconds
(No sound when both buttons are pressed at
the same time) until the display quits blinking.
Release the buttons and read Fault Codes.
This will also cancel the Fault Mode created by
self-diagnosis at power up.

Forced Mode: Press the Pwr
Freeze– Fridge buttons simultaneously
for 8-12 seconds (No sound
when both buttons are pressed at
the same time) until the display
beeps and goes blank.

Forced Compressor ***Press the Freezer button
one time at the Test Mode
to Force Compressor Run.
Measure fan and compressor
voltage at main PCB.

Sales Mode, No compressor operation
Press Power Freeze & Freezer temp buttons
simultaneously for 3 sec ( you will hear a “Ding
Dong”) to remove or put into Sales Mode. When
in the Sales Mode the Display will show “OF” “OF”
Removing power will not cancel this mode.

DC FAN MOTORS
Brushless DC Fan motors are used to save energy. The fans operate at two speeds,
High – when the ambient temperature is high and Low – when the temperature is low.
Generally, it is operated in the High mode during a day time and in the Low mode at
night. This circuit design is to protect the Main PCB from a failed fan motor.
Fan speed information is read by the Main PCB. If the fan speed exceeds 600 RPM or the speed is too slow or stopped,
the fan drive circuit is disabled, After 10 seconds, the circuit tries again with 3 seconds of DC voltage If the fan continues
this activity for 5 cycles, 10 seconds off 3 seconds on, the fan drive circuit is disabled for 10 minutes.
TO TEST THE FAN CIRCUIT VOLTAGE.
Power off and back on to check the DC voltage to the motor, wait from 10 to 60 seconds for the fan voltage to kick in,
and then check fan voltage, the average reading is 9 VDC. If you get 3 seconds of voltage every 10 seconds for the 5
fan power up cycles, then the Main PCB is good.
NOTE: You may need to put unit in FORCED FREEZE mode to activate the fans/compressor.
If the fan blade is blocked by ice, disconnect the power cord, then defrost and check the motor again.
If the evaporator is ice blocked and thus blocking the air flow, the fan will over RPM and is stopped. Remove ice and
check the motor again. If everything is clear around the fan blade, then the motor would be at fault. Continuous fan errors
will be displayed on the front panel display. PLEASE NOTE: The door switches control the evaporator fan motors.
Have them closed to test the motors. Delay time 10 – 60 seconds.
An intermittent evaporator fan door switch could cause an intermittent no cool condition.
