To physically inspect condition of White Relay, use small standard screwdriver to pry open tabs on relay cover. It is normal for contacts to look a little burnt but, if you see charring or smoke stains, replace the Relay.
It is a good rule of thumb to proactively replace the Relay any time that you have to replace a Start Capacitor that failed due to a waterlogged tank. This will lessen the chances of a follow-up service call for the customer.
