Short answerFrigidaire (including Gallery and Professional) shares its electronic platforms with Electrolux in the US. Frigidaire's own advice for most codes is the same: cut power for 30 seconds to reset. This clears most false codes. If a code comes back, the tables below show the part to check.
Notice: Installed within the last 30 days?
