Wolf L Series Code PROBE SHORTED: temperature probe failure

What PROBE SHORTED means

On Wolf L Series legacy wall ovens with the Invensys control, such as the SO30F/S and DO30F/S, PROBE SHORTED reports a temperature probe failure. The oven sees the probe circuit as shorted, so any probe-based cooking stops and the message shows. The prescribed fix is to replace the probe. The same message also appears on Wolf Legacy E Series wall ovens and Legacy dual fuel ranges, where it is ERR 09.

Common causes of PROBE SHORTED

Meat probe shorted
Probe jack contaminated or wet
Probe cable damaged

✓ One safe check you can try

1. Unplug the probe and let it cool. 2. Dry the probe jack in the oven wall with a clean cloth. 3. Run a normal bake without the probe. 4. If the message clears, replace the probe; if it persists with the probe removed, call us.

! Why to stop there

A damaged probe cable is easy to miss, and the jack is inside the cavity wall.
If the problem is in the oven, a new probe will not fix it.
A written price comes before work, with 30 days of workmanship coverage.

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.

PROBE SHORTEDPROBE SHORTED questions

Is PROBE SHORTED always the probe?

Usually, yes. The prescribed fix is a new probe. If the message remains with the probe removed and the jack dry, the circuit inside the oven needs inspection.

Can I still bake?

Normally yes, without using the probe. Clear the message by unplugging the probe and test a standard bake. If the oven stops again, call us.

Does the same message appear on other Wolf models?

Yes, Legacy E Series wall ovens show it too, and on Legacy dual fuel ranges it is ERR 09. The meaning is the same, a shorted temperature probe.
