Carrier HH12ZZ190 Limit Switch 326058-757 The Carrier EF33CW201 is aThe Carrier HH12ZZ190 Limit Switch is a critical safety component designed for precise thermal monitoring in residential gas furnaces. Engineered as a normally closed (NC) high limit control, this genuine OEM replacement part features a 190F fixed set point and a 40F differential. This means the circuit opens on a temperature rise at 190F to prevent heat exchanger damage and automatically resets when the temperature drops to 150F. Reliable thermal
