Your video says it's about how to install a new gas control valve and pipe assembly, but it only shows how to change the coils. Do you have the gas control installment video ? Thank you.
The replacement of the gas valve and pipe assembly is similar to the replacement of the coils as far as entry into the unit. The only difference will be the gas valve and pipe assembly is screwed to the base of the unit and you would need to turn off the gas and remove the gas supply from the tube assembly before it will come out. Getting into your unit is different as you would need to remove 2 screws that screw up into the front of the main top located in the door opening of the unit. Once the top is off there will be a screw on either side to remove to take the front panel off. Make sure that any wires that are taken loose are marked or take a picture of it to help with reinstall. Taking pictures to make sure that everything is in place is always a good idea. Once the front panel is of you will want to take the belt loose and lift the drum out. This will give access to the gas valve and pipe to remove it.
