Parts for Kenmore 867.778821 (867778821, 867 778821): Functional Replacement Parts

This fan and limit control is a replacement temperature-switching assembly that turns an appliance fan on and off and opens/closes at specific temperatures to help prevent overheating and restore proper airflow. What it does:

• Switches the fan or blower on and off based on temperature changes
• Opens the limit circuit to stop heating when temperatures exceed safe levels
• Restores proper fan operation when a failed thermostat causes no airflow
• Commonly used when appliances overheat, cycle the heater erratically, or the fan won't run

• Disconnect all power (and gas supply on gas appliances) before beginning work
• Compare new part to the old unit for correct terminal layout and mounting orientation
• Handle the thermostat elements carefully; avoid bending or damaging sensing bulbs
