Ideal NTC Sensor T7335D1016 10K 175214

The Ideal 175214 is a 10K NTC (negative temperature coefficient) sensor, referenced on the manufacturer's listing as the T7335D1016. It is a temperature-sensing component used on Ideal Commercial appliances, where the resistance of the sensor changes with temperature and the boiler's control board uses that signal to regulate firing and monitor operating conditions.

This sensor is listed against the Ideal Commercial Imax Plus III range, a family of commercial condensing boilers covering outputs from F95 through to F330.

• Boiler locks out or fails to fire, with a temperature-related fault code logged on the control panel
• Flow or return temperature readings that are clearly wrong, or that jump erratically rather than rising steadily
• Domestic hot water or heating output that fluctuates when demand is steady
• Short cycling, where the boiler fires and shuts down repeatedly over a short period
• Overheating trips or a boiler that runs noticeably hotter or cooler than the setpoint suggests

• Confirm the appliance model and, where available, the serial number against the compatibility list before ordering
• Check the part number on the existing sensor or the appliance's parts listing; 175214 and 95000021 refer to the same item
• Confirm the sensor is the 10K type specified for your appliance, as resistance values differ between sensor applications
