HVAC Depot Pro Tip

A furnace thermal limit switch is an important safety component that helps protect heating equipment from excessive temperatures.

If a thermal limit switch repeatedly opens, the underlying problem may involve restricted airflow, overheating, or an equipment malfunction.

Recommended diagnostic checks:

Verify the furnace model and serial number.
Confirm the original thermal limit switch part number.
Check the air filter for restrictions.
Inspect the blower motor and blower wheel.
Verify proper blower speed and airflow.
Inspect supply and return air restrictions.
Measure furnace temperature rise.
Check the heat exchanger and burner operation.
Inspect the switch wiring and electrical connections.
Confirm the replacement opens at 190°F and closes at 160°F.

HVAC Depot Pro Tip: The SWT01612 has a 30°F operating differential. Its contacts are specified to open at 190°F and close again after the sensed temperature decreases to 160°F.

Replacing a thermal limit switch without correcting the cause of overheating can result in repeated shutdowns and possible equipment damage.

Important Safety Warning: Never bypass, jumper, or install a thermal limit switch with an unapproved temperature rating. If the furnace repeatedly trips its limit switch, discontinue operation until the cause has been diagnosed and corrected by a qualified HVAC technician.

Equipment / Model Compatibility

The Trane SWT01612 is intended for select Trane and American Standard heating systems requiring this specific OEM thermal limit switch.

Exact compatible furnace model numbers have not been independently verified.

Before purchasing, confirm:

Complete equipment model number
Equipment serial number
Original switch part number
Required 190°F opening temperature
Required 160°F closing temperature
5.8 FLA at 120V electrical rating
Terminal configuration
Mounting style and dimensions
Manufacturer-approved replacement requirements

Compatibility Notice: The SWT01612 is not a universal thermal limit switch. Matching the opening temperature alone does not guarantee compatibility.

Happy Shouts From Our Thrilled Customers

William Bartlett

Cecil really saved me with troubleshooting tips over the phone. Thought I was going to have to replace the blower motor and ended up only needing a motor run capcitor. Thank you and God bless!

Verified Buyer

Riley Connolly

Cecil and Fidel were absolutely amazing and so helpful. We were happy they were open on Sunday, but was impressed with their knowledge and willingness to make sure we had everything we needed. If you need parts or service or install, I would recommend.

Verified Buyer

Cole Meger

Our AC went out during the hottest stretch of summer, and with a one-year-old at home, we were desperate for a quick fix. These guys came through big time — not only did they source the part faster than anyone else in the area, they also walked me through DIY troubleshooting while I waited. Trustworthy, knowledgeable, and run by a solid local family. As someone who owns rental properties nearby, I’ll be sourcing all my HVAC parts from them moving forward. Highly recommend!

Verified Buyer

Carl T. Droste

Had a power outage last night and during the 100 degree heat today noticed that the AC was not blowing any cold air. Pulled the capacitors to have them checked and also took video of the relay making noise even with the breaker was off. The proprietor and her staff were very friendly and helpful. She had the video analyzed and confirmed something was wrong. She checked one of the capacitors was a little low. Capacitor replacement is the biggest ticket item for HVAC repair. It is hundreds of dollars with the a capacitor only about $20.

Verified Buyer

Fuzzy Wuzzy

Cecil and his family have been a life saver. I walked in with very little knowledge on parts let alone how to repair my unit. All I had was my brother in FL who knows more than I do and Cecil at HVAC Depot. With 2 young kids at home I couldn't afford to wait for a HVAC tech. Cecil walked me through what I needed to know, even after hours when the shop closed. I successfully repaired the fan motor and replaced the capacitor. Thank you HVAC team for being totally awesome. Prices were amazing and I'm forever going to support this small family business. You and your family are what Texas is all about!!!

Verified Buyer

Linda Robinson

I called HVAC Depot and was absolutely blown away by the fast, courteous and exceptional service. They were very knowledgeable about explaining what they were doing and what had happened to the ac system. If you ever need a HVAC team they are best and they won’t hesitate by coming out and they won’t leave until you are happy with the service. Thank you so much for your excellent service. Kudos to you Michelle for your amazing customer service.
