What the L35 error code actually means

Your Dacor oven has detected a problem with the temperature sensor in the lower oven, specifically that the sensor is reading an impossibly low electrical value, which usually means there is a short circuit somewhere in the sensor or its wiring. The oven cannot accurately measure temperature under this condition, so it stops normal operation to prevent overheating. A technician will need to inspect the sensor, its wiring, and the control board connections to find and fix the fault.

Questions people ask about L35

What does L35 mean on a Dacor oven?
L35 indicates that the lower oven temperature sensor, specifically probe 3, has registered a shorted condition. The oven's control system detected an analog-to-digital value of 0x0010 or lower for 60 continuous seconds, which signals a near-zero resistance reading consistent with a short circuit in the sensor or its wiring. Normal operation cannot resume until the fault is resolved.
Is it safe to use my Dacor oven while the L35 code is active?
No, you should not continue using the oven while L35 is active. A shorted temperature sensor means the oven cannot accurately monitor its own temperature, which creates a risk of uncontrolled overheating. The oven should remain off until the sensor circuit has been inspected and the fault corrected.
How much does it cost to repair the L35 error on a Dacor oven?
Repair costs vary depending on which component has failed. A replacement lower oven temperature probe typically costs between $30 and $80 for the part alone. If the relay board requires replacement, parts alone can range from $100 to $300 or more. Adding professional labor, total repair costs commonly fall between $150 and $450 depending on the diagnosis and your location.
Can I fix the L35 error myself?
A knowledgeable DIYer can start by checking that all connectors at the relay board and probe connector are fully seated and free of corrosion. If the connections look intact, testing the probe resistance with a multimeter after disconnecting it from the circuit is the next step. Replacing a faulty probe is a manageable repair for someone comfortable working with appliance wiring, but if the relay board is involved, professional service is recommended.
Will resetting the oven clear the L35 error?
A power reset may temporarily clear the displayed code, but L35 will return if the underlying short circuit in the sensor or wiring has not been repaired. Because the fault must persist for 60 continuous seconds to trigger, a reset only delays diagnosis and does not address the root cause. The sensor circuit must be inspected and repaired before the error stays resolved.
