You want to check all your connections one more time. Then check your ground and make sure you have a good ground, this is very important. If all this is good check the low voltage side of your transformer for 24-27 Volts. Check it again at the connector going into the control board. If you have voltage there and the LED (red light) is off replace the board. You can also tasp the little black boxes on the cisrcuit pack and see if that makes a difference. Thye are relays that sometime stick, but even if it starts working you will need to replace the board.

Blower starts but not getting ignition of gas flame.
Tested Limit switch and it is in a closed positon. I believe this indicates that the limit switch is good but I am not sure. If I am correct in my assumption, what could the problem be? Also not getting any blinking lights thru the view window.

Took the lower door off and found the LED light. Turned the unit on, the fan started and I also heard like switch clicked and then smelled gas, all the time the fan is running, click reapeated about 3 times, each time smelling gas with no ignition. The unit shuts off and I have a contionus blinking red light.

what wires did you take off ?? The ignitor wires shouldn't have been B&B.They usually come with a male/female plug in fitting
