Samsung Dryer Error Code 9C1
Voltage supply error
Common Causes
- 1Low voltage
- 2Wrong outlet type
Step-by-Step Troubleshooting
- 1
Samsung electric dryers require a 240V outlet (NEMA 14-30). Use a multimeter to verify 240V AC between the two hot legs. Below 200V triggers the 9C1 code
- 2
Check the dryer power cord connection at the terminal block on the back of the dryer — a loose terminal can cause voltage drop. Tighten all three (or four) terminal screws
- 3
Inspect the circuit breaker panel — electric dryers need a dedicated 30A double-pole breaker. If one leg of the breaker has tripped, you will get 120V instead of 240V
- 4
For gas dryers showing 9C1: check the 120V outlet. Gas dryers only need 120V but are still sensitive to low voltage from extension cords or overloaded circuits
Pro Diagnostic Tip
A half-tripped 240V breaker is the #1 cause of 9C1 on electric Samsung dryers. One leg trips while the other stays on, delivering 120V instead of 240V. The drum turns (motor runs on 120V) but the heater does not work (needs 240V). Turn the breaker fully off, then fully on.
