Thank you for reaching out to UpFix. We specialize in repairing faulty electronic components. If your local technician has performed diagnostics and determined that the control board is faulty, you or the technician can safely remove it and send it to us for repair. If you are unsure whether your part is faulty, we can perform a bench test for $39.99 upon receiving the part. If we find that the unit is faulty, we will only charge you for the repair. Unfortunately, we are unable to perform diagnostics over the internet.
