Customer Questions and Answers for Power Supply, Pca by Whirlpool

Hi Johnathon. You seem to have a loose connection. This is the first issue I would tackle. Make sure you have proper 240 vac from the supply at the terminal block. Then you need to check l-1 and l-2 against white neutral for 120 vac. The clock needs 120 vac to properly light up. Then check the p1-1 power supply connection for 120 vac. between p1-4 connection neutral . If all this is solid, then double check the p-2 connector (p.c.b.). All pins need to be matched correctly and the pin connections at the jumper harness need to be checked to see if they (one- by- one) have not backed out slightly and making a partial connection. You can use a pick tool to remove the inner tang and remove the wire connector itself individually. Then pry up on the terminal tang and insert it fully back into the connector so it will make a solid pin connection. You will be able to tell if one is bent needing correction. At p-2 on the pcb board, pin # 5 is a brown wire with a non resettable fuse internally with the wire itself. Make sure there is continuity between these 2 -points as the fuse needs to be closed. This jumper goes to the clock p-7 pin connections. If nothing responds until you touch the clock control, then other than a loose connection, this seems to be the clock itself part # 4453614 Black, White is part # 4453612 The cream color is part # 4453613. You need to check all these possibilities first before ordering the clock. Please let us know how we can assist. you further. Thank You.
