What it is
The pump overrun thermostat is a Ranco control component (CL8-P1501 / K36-P2301) used on Potterton FF and Profile series boilers. It monitors boiler temperature and keeps the circulating pump running after the burner shuts down, dissipating residual heat from the heat exchanger. It is listed against replaced code 26009139.
Signs this part needs replacing
- The pump stops immediately when the burner shuts down, leaving residual heat in the heat exchanger
- The boiler overheats or trips on the overheat thermostat after a demand ends
- The pump runs continuously and will not switch off
- Short cycling or repeated lockouts during and after a heating demand
- Erratic temperature control not explained by the main boiler thermostat or pump
Before you order
- Confirm your boiler model against the fitment list above, including whether it is a natural gas or LPG variant
- Check the part number printed on the existing thermostat against CL8-P1501 or K36-P2301
- Check whether the replaced code 26009139 is marked on the old component
- Isolate the electrical supply and confirm the thermostat's physical mounting and connections match before fitting
