What it is
The Worcester Bosch 87379033990 is a temperature limiter for Greenstar 2000 Combi boilers. It is a safety cut-out that interrupts the burner circuit when the sensed temperature exceeds its set threshold, protecting the appliance from overheating.
Signs this part needs replacing
- Boiler locks out repeatedly during or shortly after a heating or hot water demand
- Overheat or high-limit fault code shown at the controls
- Burner fires then shuts down before the setpoint is reached
- Lockout clears on reset but returns as the appliance warms up
- Appliance does not restart once the overheat condition has cooled
Before you order
- Confirm the model and GC number against the appliance data badge
- Check the existing limiter's part number matches 87379033990
- Confirm whether the boiler is NG or LPG, as the fitment list covers both
- Verify the appliance is a Greenstar 2000 Combi with a Gr2300IW or Gr2301IW designation
