What it is

The Vokera 4888 is a high limit thermostat (interrupter) used in a range of Vokera gas boilers. It acts as a safety cut-out, interrupting the burner circuit if the appliance overheats. It is listed under thermostats within gas boiler spares.

Signs this part needs replacing

  • The boiler locks out or shuts down repeatedly during or shortly after firing.
  • The appliance runs but the burner cuts out before reaching normal operating temperature.
  • The boiler will not reset, or resets only briefly before tripping again.
  • Continuity across the thermostat does not change as the appliance heats up.
  • Visible damage, corrosion or a loose or broken capillary/lead at the thermostat.

Before you order

  • Confirm the appliance model against the fit list above, as several Vokera variants use different thermostats.
  • Check the existing thermostat's part number or markings where accessible.
  • Verify the fault is with the thermostat itself and not the overheat condition that caused it to trip.
  • Check the lead length and connection type against the part being removed.
