Many failure codes are caused by a faulty timer (also known as the Electronic Range Control). Sometimes, even when the failure code implies that another component has failed this can actually be a timer problem (whereby the timer is not displaying the correct fault code). If you are not sure whether the code you are seeing is due to a problem with the timer please call us, or send us an email, since we can help you determine whether the failure code is likely a timer problem or a problem with some other component. We can repair most timers so if you are sure your problem pertains to the timer (or ERC) please fill out a repair service request and send us your timer to be repaired.
