Gas Valve Pv Mv at Elijah Rubin blog

Gas Valve Pv Mv. A poor solder joint, crummy connection, burned relay contacts: Check gas supply, pilot burner, flame sense wiring, contamination of flame rod, burner ground connection. When checking for 24v at the module or gas valve, pv/mv is the common, so one lead on that and one lead on pv or mv. There's three terminals on the gas valve. Any one of those could cause it. Your gonna have to see. Be sure main gas valve (gas cock or selector arm) is turned on. With gas on and the system sparking, probe terminals pv and tr. When the burner fired up almost immdiately after the pilot came on, i got the 24 volt mv reading only if i had the black meter. You know you get 24v at both because it fires. 6+4 flame sensed out of sequence for longer than 10 seconds. While the igniter is sparking there should be 24. Correct voltage with no load (gas valve unplugged) & low voltage with load attached (gas valve plugged in) is the hallmark of high impedance in the circuit. Intermittent pilot ignition gas valves the robertshaw® 720 series gas valves, for use on intermittent pilot ignition systems, are designed.
