One of the things you must do when setting up an appointment for appliance repair, If possible you can provide us the complete model number. This is very important because when we know this number, we can attempt to pre-diagnose the issue of your appliance, and fast track the repair process. We could try bringing common parts if available in our inventory. It is also helpful to know the serial number as well as the series numbers. Those numbers are usually written on a sticker or metal plate and can be fund within your appliance.
