Hi I have a Texas furnace I recently changed the circuit board, however it stopped working and the light on the board is not coming on, I checked the power to the unit and everything seems OK. Can anyone help, I live in NY and it is very cold, I would appreciate any help that is our there

I have never heard of a Texas furnace. Does it have an Exact model number?

Yes ABA140NI5R

The brand is All Style.

Here is your factory install/service manual.

The wiring diagrams and all else is in this manual.

If the light to the board is not on then power to the unit somewhere is not being applied. Check the safety switch that is located at the blower motor access door(Called the blower door interlock on the wiring diagram). Those have been known to fail or not activate if the door is loose. I did not notice a fuse on the board but look for yourself.

If the above fail to find the problem then you will have to sound the power out problem step by step starting at the furnace switch then into the unit itself. Make sure to check all connections including any plug in item. Usually if you unplug and plug back in the contacts will clean themselves. Should be an easy find.

Do the have BIGGER furnaces in Texas than they do anywhere else?
