What Pc Ch Means
On Dacor’s counter-depth refrigerator DRF36C100SR, “Pc” and “Ch” alternating on the panel means the display panel stopped getting answers from the main board. Dacor’s service manual says the panel shows this after 10 seconds without a reply and flashes until communication returns.
Common Causes of Pc Ch
- Loose harness between the door panel and the main board
- Hinge wiring damaged by door movement
- Panel or main board failure
🔧 One Safe Check You Can Try
Turn the refrigerator off with its main switch or unplug it for a minute, then restore power. If Pc Ch returns, book service, and keep an eye on the compartment temperatures until the visit.
⚠ Why You Shouldn't Go Further Than That
- The harness runs through the door hinge to the main board at the back; checking it needs the refrigerator pulled out and panels removed.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
