Emerson Climate Technologies White-Rodgers Dryer Gas Valve 25M01A-100
A gas valve for clothes dryers with HSI systems that handles both natural gas and LP at 40 to 175 degrees F
- TypeGas Regulators
- Works with both natural gas and LP for flexible fuel choice
- Operates reliably from 40 to 175 degrees Fahrenheit
- Fits 11/32 inch and 3/8 inch gas connections
- CSA certified for safety compliance
- Replaces 18 OEM part numbers across the 25M series
Product Identity
The White-Rodgers 25M01A-100 is a CSA-certified gas valve designed for clothes dryers that use hot-surface ignition systems. It accepts both natural gas and LP fuel and replaces a long list of OEM part numbers in the 25M series.
Thermal Behaviour
The valve regulates gas flow across a control range of 40 to 175 degrees Fahrenheit during normal dryer operation. It connects to 11/32 inch and 3/8 inch gas fittings without requiring additional pressure regulation hardware.
Replacement Scope
This part covers direct substitution for OEM numbers 25M01A-130 through 25M01A-196 where listed. Installers needing a valve for non-HSI ignition systems or different temperature limits must source an alternative component.

Questions about this item
How do I install the White-Rodgers 25M01A-100 gas valve on my dryer, and what step is often missed?
Shut off the gas supply and disconnect power before removing the old valve. Connect the 11/32 in. or 3/8 in. gas fittings using pipe-thread sealant rated for LP and natural gas. The step often missed is verifying the valve orientation matches the dryer's gas flow arrow and re-testing for leaks with a soap solution after reassembly.
What maintenance or replacement will the 25M01A-100 gas valve need over time?
The valve itself has no user-serviceable parts. Periodic maintenance consists of checking the 11/32 in. and 3/8 in. gas connections for leaks and ensuring the burner orifice remains clear. Replacement is only required if the valve fails to open or close reliably within the 40 to 175 degrees F control range.
What is the first limit that appears when the 25M01A-100 runs continuously on a high-heat cycle?
The maximum control temperature of 175 degrees F is the primary limit. Once the dryer reaches this temperature, the valve modulates or shuts off gas flow to prevent overheating, making thermal regulation the first constraint under sustained use.
