Working on a Hydro Flame that will do nothing. The board on the furnace was flashing the led without a pause. The AC was flashing a red light under the cover . I pushed the emergency button and still nothing on the furnace. After reading a few other posts and suggestions it sounds like it could be the board. I do have contunity on the thermostat wires at the AC system and at the furnace. I didnt notice that there was anything on the code that was showing up on the furnace board. Any help would be great ! It is a 8940-111-DCLP

Bryant RV has the service manual online. It's worth reading:

A constant flash without any pattern means low voltage to the furnace. Check with a meter and be sure you're getting 12 volts when the furnace tries to start. Your batteries or converter may need attention.

A flashing LED indicates a lockout condition. In general, that means low voltage, ignition failure, high limit exceeded, a stuck sail switch or an internal fault on the circuit board. The flashing should be a code, repeating in a pattern of 1-5 flashes.
