Product Details

The Supco SHL503 is a high-quality replacement gas furnace limit switch designed to regulate temperature and prevent overheating in residential and commercial heating systems. This L190-40F plenum-mounted limit switch serves as a critical safety component that monitors furnace plenum temperature and cycles the blower fan appropriately.

Key Features:

  • Direct replacement for Bryant part numbers P331-2205, HH12ZA193A, HH12ZB190, and HH12ZA189
  • L190-40F temperature rating for reliable operation
  • Plenum mount design for easy installation in existing systems
  • Automatic limit control prevents furnace overheating
  • Durable construction for long-lasting performance
  • OEM-quality replacement part at aftermarket value

This limit switch is engineered to meet or exceed original equipment specifications, ensuring proper furnace operation and safety. The thermostat opens on temperature rise to protect the heat exchanger and closes to activate the blower fan, maintaining efficient heat distribution throughout your space.

I received my order in 2 days. I couldn't believe it. I would order from them again.

Pretty Easy

Everything was handled in a timely manner. My only gripe is that I wish I had received a confirmation email with a tracking number. I was waiting for it, and then the package just showed up one day. No worries though, as everything came out great. Thank you

It was all good.
