One word, several conditions
Dacor’s over-the-range convection microwave hood, the PCOR30S, shows the single generic word ERROR on its display for several distinct conditions — an incorrect clock, a failed weight-sensor cook, or a sensor-cook fault — and its own manual never assigns a distinct code to a distinct fault, so no fault code exists for this category beyond that single generic word.
The mislabeled table to ignore
An F0 and F1 pairing circulates online for Dacor microwaves, worded identically to the Classic wall oven’s own F0 and F1 codes; the match is close enough to be a relabeling of the oven table rather than a genuine microwave-specific document, so we do not publish it.
Symptom-led checks
An ERROR that appears mid-cook after a sensor-cook cycle often clears with a shorter manual time instead of the automatic sensor setting; one tied to the clock clears once the time is reset properly; and a turntable that will not turn is a motor or coupler issue separate from the display message.
When to call
A repeating ERROR display, sparking inside the cavity, or a unit that will not heat needs an experienced technician handling the magnetron and high-voltage capacitor safely, with the right genuine OEM or trusted-supplier part, since that capacitor can hold a dangerous charge even unplugged. Open the microwave diagnostics page or the error-codes library, then book microwave repair.
