# AGA overheat cut-out tripping

> AGA overheat cut-out tripping: symptoms, likely causes and how a technician diagnoses it. Occasional AGA issue. Mon–Sun 8:00AM–8:00PM. Call or text 206-427-7323.

Occasional issue — here is how we diagnose it, which parts are usually involved, and when to call a pro.

**Occasional** · Professional repair only

## What you will notice

- Zone dead until manually reset
- Repeated shutdowns
- Cooker turns itself off intermittently

## What is usually behind it

- Control thermostat failed closed, driving the zone into overheat (most common)
- Overheat thermostat itself failed (common)
- Airflow / insulation problem raising local temperature (less common)

## How a technician diagnoses it

1. Reset the manually resettable overheat thermostat and observe whether it trips again under load.
2. If it re-trips, test the control thermostat before replacing the cut-out.
3. Oven overheat thermostat phials are mounted in the roof of the roast oven alongside the oven thermocouple. Remove the phial location bracket when replacing.

> ⚠️ **Safety first:** Never bypass an overheat cut-out. It switches the neutral side and is the last line of thermal protection.
