Heil Quaker ICP 1087811 Thermal Fuse

For technicians and contractors servicing International Comfort Products (ICP) equipment, the Heil Quaker ICP 1087811 Thermal Fuse is a critical safety component required to maintain circuit integrity and prevent thermal runaway in electric furnace and air handler applications. This 249?F thermal fuse (121?C) acts as a high-limit safety cutoff, engineered to permanently interrupt electrical power to heating elements or control circuits the moment internal temperatures exceed safe operating parameters. As a genuine OEM replacement part, it ensures exact fitment and calibration, meeting the original manufacturer?s specifications for overheat protection in Heil, Tempstar, Comfortmaker, and Arcoaire systems.

Replacing a blown fuse with an ICP 1087811 thermal cutoff is essential for restoring unit operation after a high-temperature event. This non-resettable device is commonly found in ICP electric heat kits and air handlers, providing a final layer of defense against component damage and fire hazards. Utilizing authentic HVAC OEM parts like the 1087811 ensures that the temperature rating and current-carrying capacity precisely match the system?s requirement, preventing premature failures or unsafe operation associated with generic alternatives.

Key Benefits

• System Safety: Provides a reliable 249?F thermal safety trip point to prevent hazardous overheating conditions.
• Broad Compatibility: Specifically designed for ICP families, including popular models like AMFH15DHB, AMFH20DHB, and AMFH10DHB.
• Equipment Longevity: Protects expensive internal components, such as heating elements and control boards, from heat-related damage.
• Direct Fit: Eliminates the need for field modifications, ensuring a secure and efficient installation for the service technician.

Common Questions

How do I know if my ICP thermal fuse is blown?
If your air handler is running but the heating elements are not engaging, a blown thermal fuse is a likely culprit. You can verify this by using a multimeter to check for electrical continuity; a reading of "Open" or no beep indicates the fuse has tripped and must be replaced.

Can I bypass the 1087811 fuse to test the system?
Bypassing a safety device is never advised. The fuse trips because of an underlying issue, such as a failed blower motor, restricted airflow, or a stuck contactor. Always identify and resolve the root cause of the overheating before installing a new fuse.

What sub-brands is this part compatible with?
