Wolf Dual Fuel Range Recall 2019

What Is Recalled#

What Is the Risk?#

The gas manifold connection at the rear of the range can develop a slow leak due to a fitting torque specification that was revised upward after production. Creates risk of gas accumulation in the enclosed cabinet space behind the range.

This is a critical safety hazard. If your Sub-Zero oven/range is affected, take immediate action as described below. Do not delay — gas leaks can lead to explosion, fire, or carbon monoxide exposure. CPSC recall remedies are always free — there is no reason to postpone.

Affected Models#

The following Sub-Zero model numbers are included in this recall. Check your model number on the rating plate and compare it against this list:

Important: This list may not be exhaustive. Some recalls are updated after the initial announcement to add newly identified model numbers. Always verify your specific model and serial number with Sub-Zero directly or on the CPSC recall notice.

Official Remedy#

Free in-home service by a Wolf factory-certified technician to re-torque the manifold fitting to the updated specification and perform a comprehensive gas leak test. Service takes approximately 30-45 minutes.

Key points about the recall remedy process:

• The repair, replacement, or refund is completely free — you pay nothing for parts or labor.
• You do not need the original receipt for CPSC recalls. The model and serial number are sufficient to verify eligibility.
• The recall applies regardless of whether you are the original purchaser. Second owners, tenants, and landlords are all eligible.
• CPSC recalls never expire. Even if this recall was announced years ago, you can still get the free repair if your unit was never serviced.
• If the manufacturer does not respond within 30 days, file a complaint at SaferProducts.gov or call CPSC at 1-800-638-2772.

What To Do#

If your Sub-Zero oven/range model number matches the list above, take these steps immediately:

1. Check if your Wolf range model starts with DF36, DF48, or DF60
2. Pull the range away from the wall and check for gas odor behind the unit
3. Contact Sub-Zero/Wolf at 1-800-222-7820 to schedule the free recall service
4. Use only Sub-Zero/Wolf factory-certified technicians for this repair — they have the updated torque specifications
5. Have your gas connections checked annually as part of routine Wolf maintenance

Gas Leak Safety in the Home#

Natural gas leaks from appliances are among the most dangerous household hazards because natural gas is explosive at concentrations between 5% and 15% in air. A slow leak from a defective gas valve or connection can accumulate to explosive levels in enclosed spaces — such as the cabinet area behind a gas range or the utility closet around a gas dryer. The odorant (mercaptan) added to natural gas provides the characteristic rotten-egg smell as a warning, but this odor can fade in long-duration leaks or in poorly ventilated spaces.

For [Sacramento](/sacramento/sacramento)-area homeowners, PG&E provides free gas leak detection and emergency response at 1-800-743-5000, available 24 hours a day. If you smell gas from your Sub-Zero oven/range, whether or not it is related to this recall, evacuate the home without operating light switches or electrical devices, and call PG&E from outside. Never attempt to locate or repair a gas connection yourself unless you hold a California C-36 plumbing license or C-20 HVAC license.

Frequently Asked Questions#

Can my local gas technician fix this instead of a Wolf-certified technician?#

Wolf strongly recommends their factory-certified technicians for this recall repair because the updated torque specification is specific to the Wolf manifold design and requires a calibrated torque wrench at a precise setting. A generic gas technician may not have the correct specification, potentially over- or under-tightening the fitting.
