Product Details

The Lennox 10P29 is a genuine OEM 30-millivolt thermocouple designed for use in Lennox gas-fired heating systems. This essential safety component senses the pilot flame and generates the electrical signal necessary to keep the gas valve open during furnace operation.

Key Features:

  • 30-inch length provides flexible installation options
  • Generates 30 millivolts when heated by pilot flame
  • 11/32-32 male compression fitting for secure connection
  • Universal thermocouple design compatible with standing pilot systems
  • Genuine Lennox OEM part ensures exact fit and reliable performance

The thermocouple works by creating a temperature differential between the tip (heated by the pilot flame) and the base, which produces the 30-millivolt signal required for gas valve operation. This safety device automatically shuts off gas flow if the pilot flame extinguishes, preventing dangerous gas buildup. As a genuine Lennox replacement part, the 10P29 maintains factory specifications for safe system operation and preserves original equipment performance.

Fast delivery and good price. Paint cans were a little dented but the product seems to be alright.

When I get the tire and see the date code I’ll give my survey. Thanks

Great website

Simple and fast

Good price on item, fast delivery. When I did need help from customer service they were fast to answer my questions.

Very helpful very knowledgeable Thanks for all your help Outstanding!!

By my own error and partially how the product was advertised, I believed I was getting a cushion with snaps and not Velcro. I, fortunately, have some stainless snap kits and can resolve the issue. Besides that, everything went fine
