What it is

The Ideal 175129 is a control thermostat for Ideal Commercial appliances, supplied under the Ideal Spares brand. It governs the temperature at which the boiler runs, holding the appliance within its designed operating range so that heating and hot water are delivered safely and efficiently. The part is listed under thermostats, thermistors and sensors and carries the previous number 9536-3364.

Signs this part needs replacing

  • The boiler runs noticeably hotter or cooler than the setting on the control dial
  • Radiators or hot water stay cold even though there is a call for heat
  • Temperature swings widely between cycles instead of holding steady
  • The boiler short-cycles or locks out shortly after reaching temperature
  • Repeated high-limit trips or an overheating appliance

Before you order

  • Confirm the appliance model and serial number against the compatibility list before ordering
  • Check whether the thermostat currently fitted is marked 9536-3364 or 175129
  • Inspect the thermostat pocket, seal and lead for damage, and renew seals where they are worn
