Suburban SF-Series RV Furnace Gas Valve | 525044 | 161305 | OEM

Restore reliable gas flow control to your Suburban SF-Series furnace with the Suburban RV Furnace Gas Valve for SF Series (Part #525044 / 161305). Genuine Suburban OEM 12V DC gas valve for SF-Series furnaces after serial number 971303163 (roughly 1997 or later). Protects against gas leaks that can lead to fire or explosion.

What This Valve Does

The gas valve is the critical gas-flow control component in your Suburban SF-Series furnace. It:

• Controls the flow of propane to the furnace burner in response to ignition control board signals
• Opens during the ignition sequence to allow burner ignition
• Closes automatically when the furnace cycle ends or a safety fault is detected
• Prevents uncontrolled gas leaks that could cause fire or explosion

⚠️ Serial Number Verification Required

Critical fitment note: this valve is compatible with SF-Series furnaces AFTER serial number 971303163. Verify your furnace's serial number before ordering.

How to read your Suburban furnace serial number (post-January 1990):

• Suburban serial numbers after January 1990 have 9 digits
• First 2 digits = year of manufacture
• Next digits = week of the year
• Remaining digits = serial number

Important: Start with the year to determine whether your serial number is above or below 971303163. For example, a serial beginning with 98 is a LOWER serial number than one beginning with 01 (98 = 1998, 01 = 2001).
