A Dacor microwave only says error, in one undifferentiated word, and that is not a display malfunction — it is genuinely all the information this platform was designed to show.
What the official manual actually documents
The Dacor 30-inch OTR Convection Microwave Hood Use and Care Manual, covering the PCOR30S, is a real Samsung-hosted official document, and it uses only the single generic word “ERROR” on the display for several distinct underlying conditions: an incorrect clock time, a weight-sensor cooking failure, and a sensor-cook problem all trigger the identical word. There is no code table anywhere in this manual, and no distinct string is ever assigned to a distinct problem for this appliance type.
The fabricated “microwave codes” circulating online
Two sources online attribute F0 (“Shorted or jammed input device”) and F1 (“System Watchdog Circuit”) to Dacor microwaves. Look closely and these are word-for-word identical to the Classic Wall Oven and Range error codes documented in Dacor’s own Tec-Line troubleshooting sheet — a strong sign that whoever compiled the microwave list simply relabeled the oven’s codes rather than sourcing anything specific to a microwave. No Dacor microwave service manual with its own F-code table was located anywhere in this research.
Why one word for everything is not actually a problem
Because “ERROR” covers several conditions, the practical diagnostic work shifts from reading a code to observing what the microwave was doing right before the message appeared. A sensor-cook cycle that ends abruptly points somewhere different than a clock that will not hold the correct time after a power blip, even though both display the identical word.
How to actually narrow down the cause
Note what function was running when ERROR appeared — manual time-cook, a sensor-cook preset, or simply setting the clock — since that context is doing the job a specific code would otherwise do. If ERROR appears specifically during sensor-cook cycles, that points toward the weight or moisture sensor rather than the magnetron or control board generally. If the clock will not hold its setting and shows ERROR when reset, that is a different, usually simpler, problem than a cooking-cycle failure.
When to book service
An ERROR message that recurs specifically during sensor-cook cycles, a microwave that will not heat at all despite the turntable running normally, or sparking during operation are worth an experienced technician’s attention rather than repeated resets. Note exactly what the microwave was doing when ERROR appeared before you call — that detail matters more here than it would on a coded appliance. Our microwave error codes page covers this platform’s documented behavior, and our microwave appliance page covers the current drawer and OTR lineup.
