What it is
The Ideal 175128 is an overheat thermostat used on Ideal Commercial Viscount GTS series boilers. It is a safety device that monitors appliance temperature and interrupts the burner sequence if the boiler runs hotter than its design limit, preventing damage to the heat exchanger and surrounding components. It sits within the thermostats, thermistors and sensors group of Ideal Commercial spares.
Signs this part needs replacing
- The boiler locks out shortly after firing and needs repeated manual resets.
- The overheat trip operates even when the system is not calling for high output.
- Heating and hot water cut out together with no obvious fault elsewhere in the system.
- The boiler reaches temperature and then shuts down before the set point is satisfied.
- The thermostat shows signs of heat damage, corrosion or a loose connection at its terminals.
Before you order
- Confirm the appliance model and, where shown on the data badge, the GC number against the compatibility list.
- Check the existing thermostat against part number 175128 before removing it.
- Inspect any seal, gasket or retaining clip on removal and replace if it is perished or deformed.
