Why Conversion is Needed

Propane and natural gas have different combustion properties. While many new dryers ship configured for natural gas, they can be switched to LP gas using a certified retrofit kit. There are a few good reasons to go this route:

• You live in a region without natural gas pipeline access
• Your home already has large propane tanks installed
• You want backup fuel capability if pipelines suffer disruptions
• Propane grants more energy self-sufficiency

What’s in the Kit

The Whirlpool LP conversion kit (part #49572A) contains everything you need to adapt the burner, gas valve, and ventilation:

• Two burner orifices sized for propane gas
• Regulator vent cap with vapor flow limiter
• Propane conversion decal for the dryer
• Installation instructions

These parts replace natural gas-specific components on compatible Whirlpool dryer models. 

Safety First

When working on any appliance, always keep safety first to avoid personal injury or damage to the appliance or parts. Here are some safety tips to keep in mind:

• Always power off and unplug your appliance or switch off the circuit breaker before attempting any maintenance or replacement work. This keeps you safe by preventing any risk of injury from electric shock.
• Wear insulated work gloves to protect your hands from sharp metal parts, pinching hazards and debris.
• Take your time and don’t rush while working to prevent accidents and personal injuries.
• Work in a well-lit area so you can clearly see and access the interior parts.
• Clear your workspace of clutter and other obstacles. Keep children and pets away from the work area.
• Check your user manual to see if there are specific installation or safety instructions for your part or appliance. 
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause injury.
• Wear safety glasses when working with chemicals, dust or cleaning large debris to prevent injury. 
• If the appliance has recently been used, give it plenty of time for any heating parts to cool down before working on it. 
• Take pictures or make a note of wiring terminals or other connections before disconnecting to prevent any problems with reassembly.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
