I have an HEIL DC90 that decided to stop heating our house last night. The blower continues without cycling off. I've tried jumping the heat (white wire going to ts) with power (red wire going to ts) on the circuit board. Still no heat. The electronic ignition wont click. However, I also tried the a/c to see if that would come on and it didn't. Any help would be greatly appreciated.

The computer boards in some furnaces are power re-set only. It sounds like you had a safty trip, perhaps high heat,(are your filters clean?) try turning off the main power off for 30 seconds then back on. If no joy lets look for a manual reset safty, about the size of 4 dimes stacked with 2 wires and a small pen clicker size button, push it, if it continues to trip call a pro, other problems could be causing it. Luck.
Be good to your fellow man not nice there is a difference.

I found the reset. It looks like I need to call a professional. Blower blows with no heat. I checked to make sure there was sufficient air return & it seems OK.
