Alex for Model Number 79095042503 Some time ago a heard a pop followed by the smell of smoke from the back of the unit. Apparently there was some sort of short and my electronic oven control/clock-timer (part# 316455420) died. There was some black burn spots just beneath the black box above P4 and P5. I ordered a replacement timer from Sears and wired it back in exactly the way the last one was wired (Blue=P2, Blk=P1, Y=P4, R=P5, O=P6). Nothing. The thing is dead and doesn’t light up. I even tried to keep my finger down on the “clock” button and later on the “timer” button to see if it would trigger some sort of reset. Nothing. The P1 and P5 terminals on the part are receiving 110v but nothing lights up. So the new “new” part came it, I connected it, and again nothing. So yeah, it’s not the clock-timer but I have no idea what it is. Please help.
Answer Hello Alex, Before tearing into the appliance you should check at the terminal block for 240Vac from black to red. If it is not there, the issue is in the power being supplied to the unit. Check for issues in the breaker box or the junction box before the power ever gets to the unit. You will need to make sure you are getting L1 and L2 to the board. You will then need to make sure the bake and broil terminals are both passing the 120Vac to the elements. Be aware that on most units L2 will be floating on the elements at all times. For this reason it will be necessary to disconnect the connector on the bake and broil terminals on the clock to check for the voltage. The unit will have to be set to bake to get a proper reading at the bake terminal and the unit will have to be on broil for a proper reading on the broil terminal. If the voltage is not there, you will need to back up and check the elements and the terminal block for proper connections. Read More... Answered by AppliancePartsPros.com | Thursday, February 6, 2014
