Heil Quaker ICP 1008417 Limit switch

Ensure high-limit safety and operational precision in furnace applications with the Heil Quaker ICP 1008417 Limit Switch. This genuine OEM furnace technical part is engineered for a critical 160-180F temperature range, functioning as a normally open automatic limit switch that triggers during thermal overload. As a core safety component for ICP heating systems, it prevents heat exchanger damage by disrupting the burner circuit when internal plenum temperatures exceed safe thresholds. Designed for compatibility with Heil, Tempstar, and Comfortmaker units, this 180-20 LB limit switch features a durable metal mounting base and screw terminals for a secure, low-resistance connection. Whether you are performing a routine HVAC furnace repair or troubleshooting a short-cycling unit, this switch provides the exact thermal calibration required to maintain system integrity. Its automatic reset functionality ensures the system returns to operation once temperatures fall 20 degrees below the trip point, maintaining consistent airflow and safety without manual intervention.

Common Questions

What causes a furnace limit switch like the 1008417 to trip?
A trip is usually caused by restricted airflow, such as a dirty air filter, blocked return vents, or a failing blower motor, which causes the heat exchanger to overheat.

How do I verify if this switch is the correct replacement for my unit?
Check the label on your existing part for the "L180-20" designation. This ICP-specific part is a direct match for that thermal profile across multiple International Comfort Products brands.

Can I use an aftermarket limit switch instead of the ICP 1008417?
While generic switches exist, using the genuine OEM replacement part ensures the mounting depth and temperature sensitivity meet the original manufacturer's engineering specifications.
