Gaining access to Carrier furnace hot surface ignitor

Hello all,

My carrier furnace model is 58MCA060-12.

I was cleaning the furnace while looking for the igniter and found that it was behind the pvc pipe.

Can someone tell me what is the proper way to replace it if it is bad?
The igniter is blocked by the glued on pvc pipe.

Thank you

It looks there is a hex head screw that can be removed to loosen that intake pipe. You may have to cut it outside the furnace, make your repair and reconnect with a PVC coupling.

Unfortunately, the installer doesn't leave too much space to slide the pvc pipe so I have to cut in the case where I have to replace the igniter and reconnect the pipes with a 2 in. x 2 in. DWV Flexible PVC Coupling.

Question> What is the usage of the metal box on the right inner side of the furnace?
By removing this box, I may gain some extra spaces.
Thank you

Have you tried removing the four 1/4 inch hex head screws on the panel in front of the burners for a better look?

That 2x4 junction box houses your field installed high voltage connections.
