Error codeU32 / L32
ApplianceWall Oven
Quick answer
U32 and L32 report an open temperature probe 2 on Dacor wall ovens. Probe 1 becomes the primary probe and the oven can still cook and clean.
Model compatibility: Dacor reuses codes across series and model years, so U32 / L32 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Temperature probe 2 open.
Code U32 or L32 means probe 2 is open. U32 belongs to the upper or single oven, L32 to the lower, and both display TEMP SENSOR once the oven has seen 60 seconds of continuous values over the maximum bounds.
You can keep using the oven
With probe 1 acting as primary, cooking and cleaning are both still on offer. Calibration may drift a little, so food can come out hotter or cooler than normal. The manual still says to call for service.
Fault sources and fixes
Poor wiring connections at the board or harness, a worn-out probe or a broken wire are the manual’s candidates. Fixes escalate from securing the connection to replacing the probe and then the harness.
Models
Dacor 27- and 30-inch single and double wall ovens of the Dacor Wall Oven Service Manual.
Related codes
U33 is the shorted reading on probe 2, and U30 is the open reading on probe 1. U34 is probe 3 open.
