What it is
The Ariston 921036 is a safety thermostat (FIRT) for Ariston wall-hung cylinders. It monitors stored water temperature and interrupts the heating circuit if the cylinder overheats, acting as a thermal cut-out. It is listed for the AYVMA and AYVMB cylinder ranges.
Signs this part needs replacing
- The cylinder stops heating and the safety cut-out has tripped
- The cut-out trips repeatedly and needs manual resetting
- No continuity across the thermostat terminals when the cylinder is cold
- The element continues to heat with the stored water excessively hot
- Discolouration or heat damage around the thermostat body or terminals
Before you order
- Check the model and edition or date code on the cylinder data plate against the list above
- Confirm the cylinder is an AYVMA or AYVMB wall-hung unit
- Verify the existing thermostat is marked 921036
- Isolate the electrical supply and drain the cylinder as required before fitting
