624775R – FURNACE GAS VALVE (1-STAGE. STANDARD, AFTERMARKET, HONEYWELL) **OFFER 36G22, IT’S CHEAPER

If your furnace won’t ignite and you’ve ruled out the ignitor and flame sensor, the gas valve may need replacement. This is the Honeywell-branded version of a common single-stage gas valve. Note: the aftermarket 36G22-254 replaces this at a lower price — ask us at the counter.

Fits these models

• Aftermarket Honeywell-style residential gas valve — fits most furnaces that originally shipped with a Honeywell VR8200 / VR8204 series valve (Rheem, Carrier, Trane, Goodman, York, Lennox older platforms)
• Verify stage count (1-stage vs 2-stage), opening speed (fast vs slow), and pipe geometry match your existing valve
• White-Rodgers 36G22-254 is the same valve at a lower price — ask about cross-references at the counter

How do I know if my gas valve is bad?

Verify there's 24V at the valve coil terminals during a heat call -- if there's no voltage, the board (or a safety switch upstream) is the problem, not the valve. If 24V IS present and the valve doesn't open (no audible click, no gas flow), the valve is bad. Bring it in and we'll bench-test it.

1-stage vs 2-stage gas valve -- can I swap one for the other?

No. 2-stage valves have a second, lower-input solenoid (often called "low-fire") that the control board commands separately. A single-stage furnace board doesn't have a low-fire output, so a 2-stage valve will only ever run on high. Replace a 2-stage with a 2-stage; replace a 1-stage with a 1-stage.

Slow-open vs fast-open -- does it matter?

Slow-open valves ramp gas flow over 3-7 seconds, which is gentler on the ignitor and reduces flame-rollout risk on standing-pilot or older furnaces. Fast-open valves open immediately -- required on most modern HSI-equipped furnaces because the spark/HSI window is short. Match what your unit's data plate calls for.

What's the difference between Honeywell VR and White-Rodgers 36?

Honeywell VR is the older / more common platform; White-Rodgers 36 is the direct cross-replacement on most furnaces. Most VR valves cross to a 36-series equivalent and vice versa -- but verify pipe size (1/2" x 1/2" vs 3/4" x 3/4"), stage count, and connector pinout match before swapping brands. We'll match at the counter.

Can I use natural gas valves on LP propane?

Yes, but you MUST convert the valve with the LP conversion kit (different regulator spring + jets). Burning LP through a NG-set valve will cause flame impingement, sooting, and CO production. Get the conversion kit before installing.
