Goodman 1370912S – Genuine OEM Service Limit Switch (240°F, 7" Probe)

The Goodman 1370912S is a high-precision Genuine OEM Service Limit Switch designed for Goodman, Amana, and Janitrol gas furnaces. This critical safety component serves as a "high-limit" watchdog, monitoring the heat exchanger temperature and automatically interrupting the heating cycle to prevent overheating and potential system damage.

Technical Performance:

Calibrated to trigger at 240°F, this switch features an extended 7-inch insertion probe that allows it to monitor temperatures deep within the furnace cabinet where standard switches might not reach. Utilizing an automatic reset design, the switch will restore the electrical circuit once the system cools to a safe operating temperature (approximately 210°F), ensuring your HVAC system returns to service without manual intervention.

Key Features and Function:

Feature 1: Precision High-Limit Protection: Rated as an L240-30F, it strictly opens the circuit at 240°F and closes again when the temperature drops by 30°F.
Feature 2: Extended 7-Inch Reach: The extra-long probe is specifically designed for high-capacity heat exchangers to provide more accurate thermal readings.
Feature 3: Automatic Safety Reset: Automatically resumes furnace operation once temperatures stabilize, reducing unnecessary service calls for simple overheat events.
Feature 4: Genuine OEM Fitment: Manufactured to original factory specifications for a direct-fit, plug-and-play installation without bracket modifications.

🛠️ HVAC Depot Pro Tip: The "Filter & Flue" Verification

If your furnace is "limit tripping" with the 1370912S, always check for restricted airflow before replacing the switch. A dirty air filter or a blocked flue pipe are the most common causes for reaching 240°F. If the switch trips and the air filter is clean, verify your blower motor speed is set correctly for your specific heating rise.

The 1370912S is a direct OEM replacement for the following part numbers:

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.

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.
