What it is
The Potterton COM133624 is a control high/low thermostat, listed by the manufacturer under the part type Control Thermostat. It sets and regulates the operating temperature of the appliance, switching the burner between high and low fire as heat demand changes. The part is used across the Potterton Osprey family of boilers.
Signs this part needs replacing
- The boiler runs at a fixed temperature no matter where the control knob is set.
- The burner stays on high fire and does not step down to low fire.
- Temperature swings between calls for heat, with radiators or hot water running hotter or cooler than the dial position suggests.
- The appliance short-cycles or trips on the overheat thermostat during normal running.
- The control knob turns without any change in boiler behaviour.
Before you order
- Check the appliance GC number against the compatibility list, as the Osprey range uses more than one thermostat variant.
