took black wire off of cool-h and moved black wire from line-h to cool-h, is that correct?
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 2 years ago

for this one...lets put the 2 wires directly together metal to metal..and put a piiece of tape loosely over exposed metal of any kind..so black direct to black and turn power on

I thought this a 120v furnace ?

Ask Your Own HVAC Question
Customer reply replied 2 years ago
It is, okay that is the issue. This is the second incorrect motor they have given me.
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 2 years ago

whew...thought I messed up and you working on a fan coil unit.

Get new motor straightened out and then let me know

Ask Your Own HVAC Question
Customer reply replied 2 years ago
Hi, I got the new motor (120 volts) and got it installed. It won't run from the control board but will when connected directly to power. I am afraid I fried my control board either when I wired it up wrong initially and it blew a fuse or when I hooked it up and ran that incorrect 220v motor on it. Is there a way to verify that my control board is jacked?
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 2 years ago

With the wires where you had them...do you have any activity from fan on, heat or cool?
