Lockinvar TNA 151-100 COMMERCIAL WATER HEATER

in THE MAIN WALL
We have a Lockinvar  TNA151-100 that fails to fire . The igniter comes on and there is 24 volts going to the gas valve but no flame . There are 2 coils on the gas valve that I would prefer to replace instead of the whole gas valve . The gas valve is a Honeywell Type VK8115  1036 . My suppliers claims you have to buy the whole valve but this valve is set up similar to a gas dryer valve that you can easily replace the coils on. Does anybody know if this is possible instead of dropping $600.00 on a new valve

    Complete Valve

    How do you know that simply replacing the coils (if you could) will fix it? Did you ohm them out? If so, did the resistance match Honeywell's specs? What if it's a mechanical malfunction within the valve?

    You can choose to do what you want, but you cannot choose the consequences.

    ohm readings

    Yes I rang out the coils . They read infinity, sorry I failed to put that in the original question.
