Customer Question

Have a Mastercool with 1 horse 220 motor and 220 pumps. Installed Dial 7617 controller and have blower but no pump. Bought new pump, same results. Followed schematics and cannot get the pump to work. Any ideas?

Hello, send me photo's of the schematics please, I will mark them up with trouble shooting instructions.

Photo's need to be up close, well lit and exceedingly well focused.

Use the paper clip icon at the right end of the tool bar or the 'attach files' link to the left of your send buttons to

attach the photo's here.

We can go from there.
