Product Details

The First Co. E145 is a factory replacement high limit switch rated at 135°F, designed for use in First Co. air handlers and electric heat units. This thermal safety control monitors air temperature within the unit and opens the circuit if operating temperatures exceed the set point, protecting the equipment from overheating damage.

Key Features:

  • 135°F set point temperature rating
  • Auto-reset operation — resets automatically once temperatures return to safe levels
  • Direct OEM replacement for compatible First Co. air handler models
  • Designed to protect electric heat strips and HVAC components from thermal overload
  • Easy drop-in installation for qualified HVAC technicians

The E145 high limit switch is an essential safety component in First Co. HVAC systems. When the air temperature in the plenum or heat section rises beyond the 135°F threshold — due to restricted airflow, a failed blower, or other fault conditions — the switch opens to cut power and prevent further heat buildup. OEM Part Number: E145.

Lovely experience would definitely buy again

Showed up a day ahead of schedule, nice, thanks!

Easy checkout, rapid delivery, great product.

Good Experience

I bought my item from them due to the original site I bought from kept telling me my item was back ordered and didnt know when they would have one. It was easy and painless to order and received my item in a timely matter. The price was good especially seeing what other sites were charging, not the lowest price but we'll worth the extra 20 bucks I paid. Will buy from them again if they have what I need.

Ordering went quick and easy! Hopefully delivery goes quickly also!
