What Does Error Code bC2 Mean on a Samsung Dryer?

Button card error — control panel communication failure.

The button card behind the control panel has lost its data link to the main control board, so presses don't register and the dryer won't start. A loose or partly unseated ribbon connector between the panel and the main board is the most common cause, not a failed card.

Frequently Asked Questions

Can I keep using my Samsung Dryer when error bC2 appears? +
You often can for a cycle or two, but the control-panel issue behind bC2 will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes bC2 on a Samsung Dryer? +
Across reported Samsung dryer repairs, the most frequent is ribbon/connector between button card and main board loose (50% of cases), button card (UI board) failure (25%), then connector corrosion from humidity (15%). Check them in that order before replacing any parts.
bC2 keeps coming back after a reset — what should I check next? +
A reset only clears the stored bC2 fault; if it returns, the control-panel problem is still present. Move on to the physical checks — power cycle the dryer, then reseat the button-card connector — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix Samsung Dryer error bC2? +
A DIY repair typically runs $50–$130 in parts, versus $150–$300 for a professional service call, so handling it yourself saves around $100. Expect the work to take roughly 30–60 minutes.
