Never try and light a furnace when you have a glow coil ignitor. Even if you managed to do so it would reach high temp and limit would stop it. . trained technician can do this but why? If your glow coil is glowing constantly after start up than mast likely you have a control board problem. Call a technician to troubleshoot it
SOURCE: No fuel but ignitor comes on but no motor or fuel?
You must troubleshoot to see if the motor is getting 110 volts.
The problem could be the board *or* it could be the motor.
SOURCE: I have a Reddy heater pro 155.
Check all of your air filters but most likely it's the CAD flame sensor.

The ignitor is bad, there are still parts available from reddyparts.com very simple to install.

If this has a hot surface igniter, can you see it glowing? If not the igniter could be bad or the control
board for the igniter is baed.
If you are able, remover the igniter and hook it up to a 110 outlet, if it glows the problem is in the board.
If it has a board, follow the incoming power to line 1
and line 2. You will either have to splice the two leads
from the igniter into L1 and L2 or get a special spade
connector that can hold two leads on each terminal.
Plug unit in, glow coil should glow and unit should run
thats assuming you have that style of unit. Do not
attempt to do this unless you can safely perform this.
If you know of an electrician he can do this.

Just like the spark plug versions, these glowplugs need to stay on
