Hello,

 

we need toi do one thing and then retry....do you mind a hands on project...?

 

 

 

Customer: replied 6 years ago.
no problem
Customer: replied 6 years ago.
do you have info
Expert:  BillyHvac replied 6 years ago.

 

First turn power off. You will need to be able to reach to the front of the burner. In front of the burner is a metal rod with a white ceramic base. We need to wipe that rod down with steel wool before we proceed.

 

 

Customer: replied 6 years ago.
I do not see this rod
Expert:  BillyHvac replied 6 years ago.

 

do you see any wires or tubes that enter the burner area and head toward burner front?

 

 

Customer: replied 6 years ago.

yes

 

Customer: replied 6 years ago.
what now
Expert:  BillyHvac replied 6 years ago.

 

Any wire will be leading to either ignitor or sensor...this should enable you to follow wire to sensor

 

Customer: replied 6 years ago.
I found it
Expert:  BillyHvac replied 6 years ago.

 

 

Excellent....clean with steel wool....turn unit back on...then tell me if we retrieve code 7 again

 

 

Customer: replied 6 years ago.
still getting code 7
Expert:  BillyHvac replied 6 years ago.

 

Now....exhaust fan starts....ignitor glows then gas valve clicks and opens....

 

do you see ignitor glow or hear gas valve click?

 

 

Customer: replied 6 years ago.
I hear clicks and exhuast fan blows. I don't see anything glowing
Expert:  BillyHvac replied 6 years ago.

 

Well this is the issue then...your ignitor is most likely cracked which is very common.

 

It has 2 white wires that go to it. Odds are you see a fine white line across the black section of ignitor.

 

You will need to replace ignitor which is available at any heating/cooling shop.
