Hello,

My name is ***** ***** I will do my best to assist you. I am looking over your question now and will respond shortly.

Expert:  BillyHvac replied 1 month ago.

Thank you,

You have a cracked hot surface ignitor. Do you know where/what this is ?

Expert:  BillyHvac replied 1 month ago.

It is the easiest fix you can do on a furnace. Locate hsi in front of burner...remove and replace. This ignitor will be available from any local dealer.

Do you know what qvm9 is ?
Expert:  BillyHvac replied 1 month ago.

the wall hung water heater for hydronic heating

Several different formats but overall operation is same...there is a series with spark ignition instead of hot surface...

Customer: replied 1 month ago.
Okay, it came out as one piece, 2 probes and sensor ? Looks pretty worn and crusted
Expert:  BillyHvac replied 1 month ago.

You are correct. I would check to see if it will spark to ground...like checking old spark plugs...odds are it is the spark assembly.....but if no spark it is the board at other end of cable.

Customer: replied 1 month ago.
I hit switch with assembly out , had no spark
Expert:  BillyHvac replied 1 month ago.

ok did you do this during the start up 3 seconds of gas period?

Customer: replied 1 month ago.
Do do you know of a site to order part ?
Customer: replied 1 month ago.
No

To your question
Expert:  BillyHvac replied 1 month ago.

this part will only spark for 3 seconds...so you will need to run it through a start up with cable close to a ground to see if it sparks for the 3 seconds

Customer: replied 1 month ago.
Which cable would that be. The middle ?
Expert:  BillyHvac replied 1 month ago.

the one should be thicker than the other 2.

Customer: replied 1 month ago.
I have 2 identical and 1 smaller
Customer: replied 1 month ago.
My book is suggesting that it is ignition transformer
Expert:  BillyHvac replied 1 month ago.

that is why we test the spark to ground....there is a series....board determines spark time and sends power to transformer. so it becaomes which..BUT...many times you can sand and clean the spark assembly and get it working well.

The problem with this model is getting parts....unless you are lucky enough to have a local distributor

Customer: replied 1 month ago.
Ok. I will run through again. Thanks
Expert:  BillyHvac replied 1 month ago.

I really wish you the best. Hopefully you will get the spark going...that is the only issue now

Customer: replied 1 month ago.
Since I took out igniter , now not starting at all.
