Butch for Model Number mff2557hew Damper is only closing part of the time can't find themostat or control for damper.
Answer Hi Butch. The elect. control is located with the fresh food / freezer controls internally. This part # is WPW10503278. The thermistor is part # 12002355. They will sense cavity temperatures and then send information accordingly to output control fan speeds and the damper part # WPW10196393. Usually each thermistor and the damper is what is replaced. Thank you. Read More... Answered by AppliancePartsPros.com | Thursday, September 8, 2011
