UNITED STATES STOVE Co 80778 OEM Circuit Board Assembly for 5500 Series — Direct Replacement for 80558, Restores Control & Safety Functions

The US Stove 80778 circuit board assembly is the genuine OEM replacement control board designed to restore electronic control and safety functions on US Stove 5500-series stoves.

If your 5500, 5500M, or 5500XL stove is experiencing control failures, erratic behavior, or no response from the control panel, swapping in a factory-authorized 80778 board brings back reliable operation without an expensive service call. This assembly replaces the older part number 80558 and is manufactured by UNITED STATES STOVE Co to match original performance and connectors for straightforward installation.

How will this replacement board fix my stove?

Installing the 80778 board resolves issues caused by a faulty control module such as intermittent ignition signals, incorrect fan or motor control, or unresponsive buttons. Because it’s an OEM part, it fits original mounts and wiring for a faster repair compared with generic substitutes.

• Direct replacement for models 5500, 5500M, 5500XL
• Restores control logic and safety interlocks
• Plugs into existing connectors—no custom wiring
• Replaces legacy part number 80558

What does 'OEM' mean for performance and compatibility?

OEM (original equipment manufacturer) indicates the board is produced to the same specifications and quality standards as the part originally shipped with your stove. That reduces fitment issues and helps ensure the same signal timing and safety behavior intended by the original engineers.

• Factory-matched components and firmware behavior
• Same mounting and connector locations as original
• Lower risk of electrical or functional mismatches
• Backed by UNITED STATES STOVE Co part standards

How difficult is the DIY installation?

For a homeowner comfortable with basic electrical safety and appliance access, installation is typically straightforward: remove the stove access panel, unplug the old board, and plug in the new assembly. Always disconnect power and follow the stove manual or service instructions to avoid injury or damage.

• Power must be disconnected before starting
• Standard hand tools are usually sufficient
• Board mounts to the original bracket with the same fasteners
• Wiring harnesses connect directly—no splicing required

Will this board work with other US Stove models?

The 80778 circuit board is specified for the 5500 family (5500, 5500M, 5500XL) and replaces part number 80558; it is not a universal board for all US Stove models. Verify your stove model number and existing part number before ordering to ensure compatibility.

• Designed specifically for 5500-series control systems
• Replaces model 80558—check current part label
• Not recommended for unrelated stove families without confirmation
• Reference your owner's manual or service sticker for model verification
