Hello all,

I need to replace the hot surface ignitor for my gas furnace burner 58sta110-k-10116.

Question 1> What is the part number?

Question 2> When I install this new part, should I remove the old one with the mounter and then install the new on the mounter or I should directly remove the broken old hot surface ignitor only?

I saw some people remove the ignitor+mounter first, followed by replacing the ignitor.

However, I don't know for my model, what is the best practice?

Thank you

Thank you

LH33ZS004 is the part # for the only HSI that Carrier & Bryant use. Handle it as you would an egg (very fragile!) and don't touch the element with your bare hands. If the ignitor bracket clips into the burner box (older style), great care must be taken to avoid breaking the bracket. If the mounting bracket attaches to the burner box with a screw (newer style), remove the screw to take out the ignitor/bracket assembly. Make sure the gasket is positioned correctly when re-installing. Air leakage around the ignitor can create problems with ignition and/or flame carry-over.

Dear KC13,

Thank you very much for your informative answer. Here is my clarification

Please take a further look how my hot surface ignitor looks like : http://i54.tinypic.com/16itwfc.jpg

Question 1> As you can see, my HSI is round one and the part you gave me is a different shape. Are they compatible?

Question 2> Based on the image I gave you, may you take me what is the best way to replace the HSI?
Should I remove the screw one or screw two?

Thank you again

Hello KC13,

I found this image http://shortyshvac.com/images/large/LH33ZG001_LRG.JPG

Carrier hot surface ignitor P/N LH33ZG001.

Question 1> Do you think they are the one I have?

Question 2> what do you mean "Air leakage around the ignitor can create problems with ignition and/or flame carry-over." Why we make have an "air leakage" issue?

thank you

Hello KC13,

It seems that they have two products as follows

Do you know the difference between Carrier Hot Surface Ignitor LH33ZG002 and Carrier Hot Surface Ignitor LH33ZG001

thank you

Oops, I had forgotten about that one. That is the NEWEST style. I even carry one on my service truck, but I haven't had to replace one yet. If your unit is similar to the pic you attached, it is not a sealed-combustion unit, so no gasket issues. Remove screw #1 first, then change the ignitor. As I said before, handle it like an egg & don't touch the element (black part).

Hello KC13,

The picture is taken from my ignitor.

http://shortyshvac.com/index.php?main_page=product_info&cPath=27&products_id=458 LH33ZG001 $39
http://shortyshvac.com/index.php?main_page=product_info&cPath=27&products_id=1485 LH33ZG002 $32

Question 1> Do you think the new one LH33ZG001 worth the extra $$$?

Question 2> Which state you are in? I am in IL.
If you in the area where I currently stay, I would like to buy your local service in the future if my furnace doesn't work again.

Thank you again for your great helps!
