Hello, my name is Dave. The first thing to check is to be sure there is 120 vac on the Black wire and White wires at P24-1 and P24-3 on the control. If not the thermal fuse is blown. Next check for 120 vac on the input to the control transformer at P16-5 and P16-7 on the two red wires. Then check for 24 vac on the two blue wires that come from the control transformer at P16-2 and P16-3. If there is no voltage the transformer has failed. Without the 24 vac there will be no display. Let me know what you find.
Thanks Dave. I've checked the voltages and there is 120 vac present at P24-3/P24-1 and P16-5/P16-7. 24 vac at P16.2/16.3.
Hello, sorry, I stepped out for a while. Those are all the correct voltages needed to power the control and get a display.. You say you replaced the control?
Yes, the control board is brand new.
Since the old control had a display, I would put it back in to see if the new control is the problem but first if you haven't turned off the power for a few minutes try that to see if it resets.
OK, I'll give that a shot. Thanks!
Sure, let me know.
Old control seems to work fine. Maybe problems were with teh touch pad/ribbon all along. I'll send the new control back as not working.
Chris, I'm glad all is working. Hopefully they will give you your money back for the bad control.
