Carrier 1186102 Collector Box Gasket

Product Description

The Carrier 1186102 is a collector box gasket designed to seal the collector box assembly in residential and light commercial gas furnaces. The collector box sits at the interface between the heat exchanger and the inducer motor housing, and a properly seated gasket at this joint prevents flue gas from escaping into the equipment compartment. This is a direct OEM-style replacement part installed by licensed HVAC technicians during routine maintenance or when a compromised seal is identified during a combustion or leakage inspection.

This gasket is used in gas furnace applications where the collector box requires resealing due to age, heat cycling, or damage caused during a previous service call. It is typically replaced alongside the inducer motor or collector box assembly when those components are serviced. Installation is common in residential forced-air heating systems where long-term thermal cycling degrades sealing materials over time.

Key Features

• Seals the collector box-to-inducer interface to prevent flue gas bypass
• OEM-style replacement for Carrier furnace collector box assemblies
• Maintains combustion system integrity in gas furnace applications
• Designed to withstand repeated thermal cycling in high-temperature flue zones

Compatibility

Designed as an OEM-style replacement collector box gasket for Carrier gas furnace systems requiring collector box seal service.

Installation Notes

Installation should be performed by a licensed HVAC technician. Before servicing, shut off gas supply and disconnect electrical power to the furnace at the disconnect switch or breaker. Remove the old gasket material completely and ensure mating surfaces are clean and free of debris before seating the new gasket. Follow applicable local codes and the furnace manufacturer service documentation throughout the repair.
