International Comfort Products 1183833 Limit Switch

Product Description

The INTERNATIONAL COMFORT PRODUCTS 1183833 is a temperature limit switch designed to protect heating equipment from overheating conditions. This manual-reset thermostat opens the circuit at 225 degrees F and closes at 185 degrees F, providing reliable high-limit protection for the heat exchanger or burner assembly it monitors. When the set-point temperature is exceeded, the switch opens and must be manually reset before the system can restart. Licensed HVAC technicians install this part as a genuine OEM replacement during service or repair calls on affected units.

This limit switch is suited for residential and light commercial heating applications where high-limit protection is required. It serves as a direct OEM replacement for units that call for the 1183833 limit switch, maintaining the original safety and operational parameters of the heating system. Technicians replacing a tripped or failed high-limit device will find this part restores factory-specified cutout and reset temperatures.

Installation Notes

Installation should be performed by a licensed HVAC technician following all applicable local and national codes, including NFPA 54 and IFGC guidelines. Shut off power to the unit at the disconnect and allow the heat exchanger to cool completely before handling the limit switch. Inspect the cause of any prior high-limit trip before resetting the device, as repeated tripping indicates an underlying airflow or burner problem. Do not bypass the limit switch under any circumstances.
