About three weeks ago, the control wouldn't start. I replaced the cpu power supply and it fixed it. Today, I turned on the main power and I heard a pop and crackle noise. Then, without thinking I tried to turn the control on and heard a similar noise. Now the control won't come on and the cpu power supply is burnt and the 240/24 power supply on the cabinet door is too. The 240/24 power supply is getting 220 volts. I unhooked the wires coming off the output side of the 240/24v supply and ohm'd the -24v wire to ground and measured 285 ohms. Does anybody have any ideas where the short may be or any other ideas? Thanks in advance.
