DCS Dual Thermal Gas Valve 210782

[Waterrat]

Hello,

I had a broiler ignitor burn out on a DCS RGS-366SS range. I got that replaced but when I went to turn on the broiler it didn't glow. I started checking the Dual Thermal Gas Valve 210782 which is oriented like an upside down T with gas line feeding the broiler coming out of the top. On the left hand spade terminals I'm getting 0 volts with broiler off and 120 volts with broiler on. With power disconnected and wires off the terminal, I'm getting no continuity between the terminals. Should the spade terminals on the left hand side have continuity?

I'm assuming that power applied to the left terminals should open the gas valve to the broiler and close a contact to provide power to the ignitor?

Do I have a bad valve or do I need to be trouble shooting it differently?

Thank You,

Ron

This safety gas valve operates by current passing through a bimetallic strip between the two terminals. With differing rates of expansion, the strip will "snap" once it heats up enough and release the gas to flow to the now glowing ignitor. I'll bet during the incident of the ignitor burning out previously the gas valve got damaged internallly. You will note that the gas valve uses tamper-proof torx screws to hold it together. I like to do post repair autopsies of parts which  I am uncertain of their workings. Go ahead and open it up but please do not return it to service.

Hello fellow appliance enthusiasts.

I have a this DCS natural gas range RGS-366, and have used this forum to replace the oven and broiler igniters in the past. Recently, while in use we heard a kind of "whump" inside the oven (can't remember if it was the oven or the broiler; only one can be on at a time). I turned it off, sniffed for gas, checked the surface burners, and turned the oven back on, which worked successfully. Later I checked the broiler and it wouldn't turn on. When I removed the igniter I saw it was broken and I replaced it.

Now the igniter lights up quickly, but as soon as gas is admitted the broiler makes an unusual and concerning noise, almost like there's too much air in the mix (it actually almost blows out the flame). The problem is repeatable every time. Any thoughts on what this might be? Dual gas valve? Broiler element? Too much air in our gas supply (which happens here in the winter; listen to the surface burners "frothing").  The oven and surface burners still operate without any issues.

Any advice sincerely appreciated.
