The relay is built into the control board John, Unfortunately the control board is not serviceable.
The model number you supplied is not coming up on my system so I cant find the part number for the clock (control board)
The number you supplied appears to be a Canadian model number, take the model number to order the control to a local sears service center or to a local appliance parts dealer.
If the clock is on a control panel in the rear pull the unit out from the wall, take the panel out in the rear, you will then have access to the control (clock)
