Nordyne won't turn on

[Ric Winegar]

Hello,
I have a Nordyne C1QA-030U-B, a furnace with a/c. Nothing is working. No heat, no a/c, and the fan will not come on when switched from "auto" to on.
I have replaced the thermostat, and checked to make sure the breakers inside the house are in the "on" position. Still nothing.
Please help, it is getting hotter outside.
Thanks,
Ric

Hi Ric,


Test primary-line side of transformer for 120vac or 240vac.


If there, test secondary-load side for 24-28vac.


Either transformer has blown, a fuse has blown or a loose wire on power or neutral side of 24vac low voltage circuit.



Thanks,
Robert
