Having some problems with a heatnglo sl-550tr-ipi-e natural gas fireplace. Pilot light comes on and stays on. Main burner will not turn on. I went through a trouble shooting manual and the gas valve passes the ohm test. However the way they describe to check for voltage at the gas valve is where I’m unsure. It says to slide the wire back slightly off the spade and it should give 1.6 volts to open the valve and 0.3 to keep it open. As soon as I check for voltage it drops to zero, however, when I remove and test voltage at the wire directly when it is not attached to the gas valve I get a small voltage measurement on the meter. Approx 1 V. Any ideas on these complicated intellifire setups? Thanks.
