It seems as if my igniter chit the bed on my Astoria Bay pellet stove fireplace insert. It's 3 years old and I use a remote thermostat, so I'm assuming it has simply worn out. Naturally, I'm going to test it to be certain before I dive in to replacing it, but I wanted to know how difficult it is to access the igniter?? What pieces have to be removed to gain access?? Thanks for your help in advance!!
