A Cleveland 108591 Thermocouple allows temperature monitoring in various positions, ensuring a stable and dependable reading.
The Cleveland 108591 Thermocouple supports ignition, flame proving and the gas safety circuit by providing the temperature-related input the equipment uses to confirm proper burner operation. Its K-type construction is important because consistent sensing is essential for stable heating performance and for maintaining safe, reliable response within this ignition and flame-sensing function category.
The Cleveland 108591 Thermocouple could be failing if the unit is not heating, is not holding temperature, shows inaccurate temperature readings or displays heating or probe-related errors. Visible signs may include recurring error messages, erratic temperatures or a faulty or shorted probe condition, which might be improved by using a real OEM replacement built for long service life.
