o keefe and merritt safety valve price

My vintage gas stove has safety systems for the oven and broiler. I thought it was of one of the things  that CP (Certified Performance *) trademark of the Gas Appliance Manufacturers Association is about. “CP” stoves have a long list of safety and performance features which evolved over time. (see page bottom)

As far as I could tell, it meant, for any reason, if the gas flow to the stove stops while the oven or broiler was on, when the gas flow is re-established,  raw gas does not quickly fill up the oven or broiler cavities.  Lots of raw gas in an enclosed space can cause an explosion if it is suddenly ignited.

OK. Duly noted. The problem is sometimes the entire safety system fails, the oven doesn’t turn on or doesn’t stay on. Many people don’t understand why or how to fix it. They just know their oven or broiler won’t light. Very frustrating. Playing with gas stove problems is not for the faint of heart. Playing it totally safe means locating a vintage stove expert, which in most circumstances is NOT your standard appliance tech. But these stoves are not that complex. If you’re confident in understanding a few basic concepts and respect with gas can do when you are too sloppy, you might be able to either fix the problem or explain enough to a plumber or gas technician that they can fix things.

At the page end is a set of drawings that might help you understand what is involved in a working and non-working safety system.  There are several separate components that have to be working. If the oven or broiler won’t light or the oven is not keeping the right temperature, , a conversion between NG and LP, one of more of those components might have failed.

The problem may be simple. Greasy or ashy buildup could be causing a problem. The standing pilot and thermocouple that sits right next to it, can over time, accumulate gunk. After all, they’re sitting inside the oven near the oven’s main burner. Who knows what gremlin dirt may have been deposited when the door is closed?
