Ideal Thermostat Knob 079838

The Ideal 079838 thermostat knob is the hand control that fits onto the thermostat spindle on Ideal Commercial appliances, allowing the user to set the required boiler temperature. It is supplied under the reference ATE0008 and is listed by the manufacturer as a thermostat knob. The knob forms the user-facing part of the temperature control, so its markings and its grip on the spindle directly affect how accurately the appliance can be set.

• The knob turns freely on the spindle without changing the temperature setting
• Cracks, splits or a broken centre boss where the knob grips the shaft
• The knob has come away from the control panel or will not stay seated
• Temperature markings have worn away, making the setting difficult to read
• The control feels loose or gritty when turned, indicating a damaged knob or spindle fit

• Confirm the part number 079838 and the reference ATE0008 against the existing knob or the appliance documentation
• Check the appliance model against the compatibility list before ordering, as the same control panel can use different knobs across the range
• Inspect the thermostat spindle and any retaining clip or spring while the knob is removed, and replace these if they are worn
• Keep the appliance isolated from the electrical supply while the control panel is opened
