Dacor DOP Range Code C-30: Board Sensor Open or Shorted

Medium · inspection needed

Code: C-30
Appliance: Range
Brand: Dacor
Warranty: 30-day workmanship

What C-30 means

If a Dacor DOP range (DOP48T960GS, DOP48C96DLS) or the DOP30T940IS induction range shows C-30, the sensor that watches the temperature of the main control board shows an open or shorted circuit whenever the oven is running. The control watches its own board temperature to protect the electronics, and without a valid reading it cannot do that. The oven may stop heating until the code is cleared.

Common causes of C-30

The temperature sensor on the control board
The connector that carries the sensor signal
The control board itself

✓ One safe check you can try

1. Rotate the mode knob to Off, then fire up the range again. 2. If C-30 appears again, cut power at the breaker for 30 seconds or longer, then restore it. 3. If the code stays, leave the oven off and reach out and we will schedule a visit.

! Why to stop there

The sensor sits on the control board, so the question is whether the sensor, its connection or the whole board needs attention, and we test before we replace.
We put the price in writing first, so you decide before any work begins.
If the code appears only after long cooking, tell us, because heat can matter.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

C-30C-30 questions

What is C-30 on my Dacor range?

The control board's own temperature sensor shows an open or shorted circuit during cooking. The control uses this reading to protect itself, so the range may stop heating.

Is C-30 the same as C-31?

No. C-30 means the board sensor itself reads wrong. C-31 means the board temperature is actually unusually high.

Will a restart fix C-30?

It sometimes clears a brief glitch. If C-30 returns, the sensor circuit has a real problem, and we test it.
