Troubleshooting Registered Product Issues in Mobile Link

This article consolidates common “registered product” issues seen in Mobile Link and provides potential causes, troubleshooting, and resolutions. Each section links to a dedicated Help Center article for deeper, step-by-step guidance.

How does this happen?

Common causes include entering the wrong serial or MAC (reading a similar digit/letter, using paperwork instead of the data plate), scanning a nearby unit’s QR code, enrolling under a different email/account than intended, the previous homeowner or dealer never removing the unit from their account, pre-registration during testing or a prior sale, refurb/return units that retained a prior registration, or transposed data entered during installation or activation.

Important: Installers should never register a generator to their company or use "dummy" info when entering Mobile Link registration information. Installed home standby generators should always be registered to the homeowner, even if the generator is dealer managed.

Incorrect product registration symptoms

The following symptoms can occur when the wrong generator is registered to an account: 

How can I verify that the correct generator is registered?

Confirm the serial number (SN) shown in Mobile Link matches the SN printed on your generator’s data tag. Use the steps below to check both places.

Step 1: Check the serial number in Mobile Link

1. Open the Mobile Link app and sign in.
2. Go to the Dashboard and tap your generator’s tile to open its details.
3. Open Technical Specs / Generator Details and locate the Serial Number field.

Note: If you’re using the Mobile Link web app, open your generator’s details page and view the Technical Specifications section to see the serial number.

Step 2: Verify the serial number on the generator

1. Locate the generator’s physical data tag and read the serial number exactly as printed (watch for look-alike characters like 0/O and 1/I).
2. For home standby units, the data tag locations are shown in our Help Center guide: Where do I find the serial number on my air- or liquid-cooled standby generator?
3. Compare the serial from the data tag to the one shown in Mobile Link. They must match exactly. If they don’t, remove the wrong product from your account and re-enroll using the correct product.

“Generator is already registered” message

Brief description: During device enrollment or account setup, Mobile Link reports that the generator is already registered.

Common causes:

• The generator is still associated with a previous owner’s account.
• The same owner has multiple emails/accounts; the unit is tied to a different email.
• A deleted account or prior activation left the serial number enrolled on backend services.

Troubleshooting:

• Confirm you are signing in with the email originally used for generator registration. If you don't know what email was used during registration, have your serial number ready and contact Generac customer support at 888-436-3722.
• Verify the exact generator serial number being entered.
• Check whether the previous homeowner still has the unit on their Mobile Link account.

Resolution:

• Remove the generator from the current/previous account (see the “Remove a product” section below).
• If the unit belongs to a prior owner and you cannot contact them, please call or email Generac Customer Support and include your Name, Email, Phone, information to prove your address (such as a utility bill), and a picture of the generator's data tag.

Troubleshooting:

• Reconfirm the generator serial number on the data plate.
• Ask the customer whether the unit may have been previously owned or returned.

Resolution:
