Dacor Oven Error Code L32

L32 indicates that the lower oven temperature sensor probe 2 is in an open circuit condition. The relay board's analog-to-digital converter has registered a value of 0x3F0 or higher for 60 continuous seconds, which signals that the probe is disconnected or has failed. The oven cannot regulate lower oven temperature without a functioning sensor reading.

No, you should not use the oven while L32 is active. Without a functional temperature sensor, the control system cannot accurately monitor or regulate heat in the lower oven cavity. This could result in overheating or unpredictable temperature behavior, creating both a safety risk and potential damage to food and the appliance.

Repair costs vary depending on the root cause. Replacing a lower oven temperature probe typically costs between $50 and $150 for the part, plus labor if a technician is involved. A relay board replacement can range from $150 to $400 or more for the part alone. Adding professional labor charges, total repair costs generally fall between $150 and $600 depending on the component and service provider.

Some causes of L32 are DIY-friendly, such as reseating a loose connector at the probe or relay board. However, replacing the temperature probe or the relay board requires accessing internal components and working with electrical connections, which is better suited to technicians with appliance repair experience. Always disconnect power to the oven before inspecting any wiring or connectors.

A power reset may temporarily clear the error display, but L32 will return if the underlying fault is still present. The code is triggered after 60 continuous seconds of an out-of-range A/D reading, so unless the probe, connectors, or wiring are repaired, the fault will reappear once the oven goes through its startup or heating cycle.
