HVAC Depot Pro Tip
A temperature-activated switch that opens or closes unexpectedly may indicate an equipment operating problem rather than a defective switch.
Before replacing the Carrier HH18HV131, determine the switch's function in the manufacturer's wiring diagram and inspect the equipment for abnormal operating temperatures.
Recommended diagnostic checks:
- Confirm the complete equipment model and serial number.
- Verify the original switch part number is HH18HV131.
- Identify the switch's function in the electrical schematic.
- Inspect the switch terminals and wiring connections.
- Check for abnormal heating or temperature conditions.
- Test switch operation according to manufacturer procedures.
- Verify the replacement matches the original temperature and electrical ratings.
HVAC Depot Pro Tip: Temperature-activated switches may look similar while having different operating temperatures, reset characteristics, or electrical configurations. Always match the OEM part number and manufacturer-approved specifications.
Important: Never bypass a temperature safety switch. Disconnect electrical power before servicing and correct any underlying equipment malfunction before returning the system to operation.
Equipment / Model Compatibility
The Carrier HH18HV131 is intended for select Carrier HVAC equipment requiring this specific OEM temperature-activated switch.
It may also be used in Bryant or Payne equipment where the manufacturer explicitly specifies HH18HV131.
Exact compatible equipment models have not been independently verified.
Before ordering, confirm:
- Complete equipment model number
- Equipment serial number
- Original switch part number
- Required temperature ratings
- Reset characteristics
- Electrical terminal configuration
- Mounting dimensions and design
Compatibility Notice: HH18HV131 is not a universal temperature switch. Manufacturer-approved compatibility must be confirmed before purchasing.

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!

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.

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!

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.

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!!!

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.

My AC went out in our home on Friday night. I went out and got the capacitor details and took them here first thing Saturday morning. Lady at the counter was friendly and had the capacitor I needed! When I got home, I installed the capacitor and AC is all good!!
