What it is
The Baxi 5107803 is a control thermostat supplied in potentiometer form for Baxi Bermuda back boiler units. It sits in the appliance's temperature control circuit and is adjusted by the user to set the heat output the boiler delivers. It is a direct replacement item for the control dial position on the Bermuda 51/5 Outset and Inset 3 50/5 and 50/6 ranges.
Signs this part needs replacing
- The boiler does not respond when the control dial is turned up or down.
- Heat output stays fixed regardless of where the dial is set.
- The dial turns loosely, feels rough, or has no defined range of movement.
- Heating runs erratically, with the appliance cycling in a way that does not match the dial position.
- The control has become intermittent, working only at certain points on the dial.
Before you order
- Check the GC number on the appliance data badge against the compatibility list to confirm the correct variant.
- Confirm the model name on the badge matches one of the Bermuda 51/5 Outset or Inset 3 50/5 and 50/6 listings.
- Note the alternative number 1117644 when cross-referencing older documentation or stock records.
