The Coleman 7990‑328 Gas Valve is an OEM replacement White‑Rodgers 36J29‑701 combination gas valve used on many Coleman, Evcon, York, Luxaire, and Fraser‑Johnston furnaces equipped with electronic ignition systems. Exact replacement for older model Mobile home furnaces

This versatile gas valve is field‑convertible between Natural Gas and LP (Propane) by reversing the internal conversion stem, eliminating the need for separate gas valve models. Designed for dependable ignition performance, it precisely controls gas flow to the burners while interfacing with modern furnace ignition controls.

The updated White‑Rodgers design may look different from older valves but serves as the approved replacement for numerous discontinued Coleman gas valves. It features a 1/2" gas inlet on the right side and a 3/8" outlet on the back left, matching many original furnace gas train configurations.

Ideal for replacing failed gas valves causing ignition failures, sticking valves, intermittent burner operation, or gas flow issues.
