Jenn-Air Oven Error Code 1c5c

The 1c5c code indicates a VCC or ground fault detected at a test point on the electronic control board. VCC is the supply voltage that powers the board's logic circuits. The control board flags this fault when it measures a voltage or ground reading outside the expected range at that test point. The oven's control takes no automatic corrective action when this code appears, so manual diagnosis is required.

Because this fault involves a potential issue with the control board's internal power supply or grounding, continued use carries some risk of unpredictable control behavior. The control takes no automatic action in response to this code, so the oven may appear to function normally, but an underlying electrical fault on the board should be diagnosed before relying on the oven for regular use.

Repair costs depend on the root cause. If the fix is a simple wiring reconnection or ground wire repair, costs may be minimal, primarily covering a service call in the range of $75 to $150. If the control board needs replacement, parts and labor combined typically range from $250 to $600 or more depending on the specific board and local labor rates.

Some causes of this code, such as a loose harness connector or a corroded ground wire, can be addressed by a knowledgeable DIYer comfortable working around appliance electrical systems. However, if the fault is traced to a failed component on the control board itself, board replacement is generally needed and is best handled by a qualified technician. Always disconnect power to the oven before inspecting any wiring or connectors.

Disconnecting power to the oven for several minutes and restoring it may temporarily clear the code if the fault was intermittent. However, if the underlying cause, such as a damaged wiring connection or a failing control board, is still present, the code will return. A reset alone does not correct the electrical condition that triggered the fault.
