Im having trouble with a Lennox furnace, there is two together and the twinning module is disconnected. I ran my thermostat wires to the one furnace and it would not come the led light is flashing normal and the induce draft fan is running but there is no call for heat.

Appears to be obvious that heat call/wire is missing.

With the twinning kit removed one blower will run backwards and trip the limit behind the blower.

The thermostat works with the other furnace the led ia reading normal when it should be flashing for a call for heat. The blower on this furnace has been jumped and,its just blowing.
