Dacor Range, Oven, Cooktop Error Code L32

L32 indicates that the lower oven temperature sensor, specifically RTD 2, has an open circuit condition. This means the control board is receiving no usable resistance signal from the sensor. The fault is typically caused by a wiring break, a loose connector, or a failed sensor element. The oven will not function normally until the open circuit is located and repaired.

It is not recommended to use the lower oven while the L32 code is active. Without a functioning temperature sensor, the control board cannot regulate oven temperature accurately, which creates a risk of overheating. The oven may refuse to operate at all as a safety precaution, depending on how the control board responds to the fault.

Repair costs depend on what component has failed. If the fix is simply reseating a loose connector, there may be no parts cost and only a service call fee, which typically ranges from $75 to $150. Replacing the RTD sensor itself usually adds $50 to $150 in parts. If the wiring harness needs replacement, total costs including labor can range from $200 to $400 or more depending on your location and service provider.

A knowledgeable DIYer can start by inspecting the wiring connections at the lower oven RTD and along the harness routing for obvious breaks or loose connectors. If reseating connectors does not resolve the fault, testing the sensor with a multimeter requires some comfort with electrical diagnostics. Replacing the RTD sensor or wiring harness is a moderate repair, but working around oven wiring should always be done with the appliance unplugged from power.

Cycling power to the oven may temporarily clear the displayed code, but the L32 fault will return if the underlying open circuit condition has not been corrected. A reset is useful for confirming whether the fault is intermittent, but it is not a fix. The wiring and sensor must be inspected and repaired to permanently resolve the error.
