I have a true t 23-f-rc freezer. When the unit is plugged in it trips the breaker to the unit. I have removed all controls and the fans from the curciut and it still trips the breaker. Upon investigation I can remove the wire from the number four side of the defrost clock that is basically the power going to all controls and it does not trip. If I have the wire connected and all of the control disconnected it trips the breaker. I can disconnect the white wire coming back down the case and it does not trip the breaker. I am wondering if the frame heaters are shorted out but I am unable to determine which wire goes to them. I need a wiring diagram for this T-23-f-rc unit. If anyone has one and could help me I would be most thankful.
