Bertazzoni Ranges 30:150 Error: Meat probe jack short circuit
What Does 30:150 Mean? The code 30:150 appears on Bertazzoni Professional Series dual-fuel ranges with TFT digital displays — most commonly the PROF366DFSROT and similar models. It signals that the control board’s food probe monitoring circuit has detected a short or open condition on the meat probe receptacle. The fault can appear even when no […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. The oven cannot maintain accurate temperature control while 30:150 is active. Schedule service within a few days — a shorted probe receptacle will cause the fault to return on every use until replaced.
Can I reset the code?
Yes. A 2-minute circuit breaker power-cycle clears the fault flag, but the code will return on the next use if the probe receptacle is internally shorted. Replacing the receptacle permanently resolves the fault.
When to stop immediately?
Stop if you notice: Oven temperature becomes uncontrolled with 30:150 active, Fault appears during every cooking attempt without a probe plugged in.
Symptoms You May Notice
Oven will not hold temperature and shuts down unexpectedly
The oven cavity may heat initially but then cuts off as the control board detects the abnormal probe jack signal and triggers a protective shutdown to prevent sensor-circuit damage.
Display shows 30:150 even with food probe unplugged
The fault persists when no probe is connected because the receptacle itself is internally shorted, continuously presenting an invalid reading to the probe monitoring circuit on the control board.
Error reappears immediately after every power-cycle reset
Unlike a transient software glitch, 30:150 returns within the first heating attempt after reset because the physical shorted receptacle keeps triggering the detection circuit.
Possible Causes
Meat probe receptacle corroded or internally shorted
Repeated heat and steam exposure inside the oven cavity has corroded the probe jack's internal contacts, creating a low-resistance path that the control board interprets as a shorted probe.
Requires ProfessionalDamaged probe cord left plugged into the jack
A cracked or broken probe cable still seated in the receptacle continuously shorts the probe monitoring terminals, triggering the 30:150 fault even during normal bake cycles.
DIY PossibleSafe Checks You Can Do
-
1
Remove the food probe if plugged in
Open the oven door and check whether a meat probe is currently seated in the interior probe jack. If it is, unplug it completely and power-cycle the range at the circuit breaker for 2 minutes, then test whether the fault clears.
If the fault clears after removing the probe, the probe cable itself is damaged — replace the probe before the next use.

2
Power-cycle with probe jack empty
Ensure no probe is connected, then switch the circuit breaker off for 2 full minutes and restore power. Attempt a bake cycle and note whether 30:150 reappears.
If the fault returns with the jack empty, the receptacle is internally shorted and requires professional replacement — the oven should not be used until repaired.
When to Call a Professional
Contact a qualified technician if:
- 30:150 reappears immediately after reset with the probe jack empty
- Visible corrosion or burn damage inside the probe receptacle
