Miller furnace trouble

[tommytrucker]

I have electronic ignition problems with my city gas Miller hot air furnace.
I was wondering how much voltage should be measured from the output of the circuit board to the gas valve.

I thought the output should be 24 volt. I measured 4 tenth or .4 on my multimeter voltage when the honeywell single try board sent juice to the valve.

Do I need to replace the circuit board or should I look elsewhere for more
problems?

It sounded like the spark ignition was working OK.

Please advise it would really be appreciated.

The furnace is now repaired. It was a broken element in the burn box.The circuit couldn't be completed. The gas valve wasn't being opened due to lack of spark.

Thanks for the response
