How to Reset the PC Power Supply
Description of the problem:
The PC fan isn't running, all power appears to be off (even though it is plugged in), and there is a possibility that the power supply was shorted out.
Solution:
Reset the power supply by following these instructions:
Unplug the control power
Turn and hold the key for 10 seconds
Wait for 10 minutes
Connect power and turn the key to power on the control
If the control doesn't power on, continue below
The next step is to remove the power supply from the PC (search Knowledge Base for instructions to remove PC)
After removing the power supply, we want to bench test it with only the power cord plugged in
Hold the power button down for 20 seconds and release
Wait for 10 seconds and then press the power button to power on the supply
If the power supply still doesn't power up, it is presumed to be inoperable
This is a standard 300W PC supply and should be available from a local PC supply store. Just verify the physical dimensions are comparable.
