high severity
Smeg models: Smeg ovens have a temperature probe at the rear cavity wall. The Portofino and Victoria ranges are dual-fuel (gas hob, electric oven). Smeg's rapid pre-heat mode activates multiple elements simultaneously — a louder-than-expected preheat phase is a normal behaviour of this feature.
Common causes
- Voltage sag or spike on the supply line
- Loose connection at the terminal block
- Utility power quality issue
Step-by-step fix
- Power cycle.
- Tighten connections at the terminal block if accessible.
- Note whether the issue correlates with other high-draw appliances starting (dishwasher, A/C) — a sign of inadequate wiring.

Screwdriver set
Prevention

When to stop DIY
