🛠️ HVAC Depot Pro Tip

Do not match a furnace gas valve by pipe size alone. A replacement must also match the fuel type, voltage, staging, operating characteristics, and equipment requirements.

For this valve, the primary identifiers are:

Cat #: 16Y31
Part #: 105601-01
Fuel: Natural Gas
Voltage: 24 VAC
Stages: 2-Stage
Connections: 3/4" x 3/4"
Operation: Fast Open

This is a two-stage valve, so it should not be substituted with a standard single-stage gas valve simply because the connections and voltage are the same.

Gas-valve installation and adjustment should follow Lennox service procedures and applicable fuel-gas codes, including proper leak testing and verification of manifold pressure and combustion.

Equipment / Model Compatibility

The Lennox 16Y31 / 105601-01 is intended for select Lennox gas-fired equipment requiring a 24 VAC, two-stage natural gas valve with 3/4" connections.

Typical applications include compatible:

Lennox gas furnaces
Two-stage furnaces
Natural gas heating systems
Electronic ignition systems
Residential forced-air heating equipment
Lennox equipment specifically calling for 105601-01

Always verify the complete furnace model and serial number before ordering.

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.
