New World(Stoves) Twinline Gas Oven About 9-10 yrs old
The programmer on this appliance failed almost immediately when it was first installed. However the appliance still worked ok.The oven section failed to work at all just recently, on inspection I found that the "One shot blow devices" attached to the wire wound resistors had gone open circuit. I replaced the programmer, the cooling fan control circuit board and the mains interference filter,all of which I had bought as spares but not fitted (as I stated the appliance worked fine).The oven worked perfectly for 24 hrs, then again refused to function although the grill section did.On doing a continuity check I again found that one of the "One shot blow devices" attached to the wire wound resistors had gone open circuit. I connected the fan directly to the mains, and it ran perfectly OK, did not get warm, no funny noises or anything else to give me cause to suspect it to be at fault.
Moreover, when the grill is in operation, the fan comes on as it should under the control of the resistor and thermal switch (mounted on the same board as the wire wound resistors), and cuts out after a set period when the grill has been switched off. I am therefore somewhat at a loss to pin down exactly what is at fault, the programmer is not receiving any elec. supply, because the one shot devices have isolated it to give a clear indication of a fault and hence prevent the oven functioning.
It grieves me to have to turn to people int the US for help, but the company who are now responsible for service support on this appliance are completely useless as far as assistance is concerned, they won't put me in touch with one of their service engineers, and because I live on a boat won't come out to me anyway !!. Without someone's technical help I cannot progress the problem, I am a qualified electro/mechanical engineer and will be able to fix the appliance with a bit of help. The gas side of the oven is not involved, the fault I am sure is solely electrical.
I look forward in anticipation to your response.
Kind regards John Hall

Egnition is a push button to a spark generator, If this is electric, the obvious answer would be turn off the electric. This should not affect the gas unless if is temp controled by electric. Usually the temp is set gy a gas regularor controlled with a knob and set before gas is ignited.
According to the circuit diagram on page 31 of the handbook, power for the ovens passes through the clock. The power feed is direct for the actual clock but via a seperate Thermal Cutout for both the top and bottom ovens. I think it is highly unlikely that both Thermal Cutouts have failed at the same time. I would try turning the power off totally to the oven for a while and then turning it back on, set the time and ensure the oven is in manual mode. As the top and bottom ovens have seperate controls after the Programmer and both are not working, it has to be the programmer that is not extending the power through to the rest of the oven.
A lot of times the problem is with a dirty or a clogged burner. Make sure the burner is clean. If you have a pilotless model, it uses a spark igniter to ignite the gas, which works in a combination with a spark switch (located on the burner gas valve) and a spark module. Because it is not simple to test these parts and find out which one is defective, we recommend to contact a professional appliance technician.
i am having the same problem but i have been told it is the cooler fan so i have ordered a new one,the fan unit requires running as it is linked to safety sensors the equal air preasure and if not equiled by the fan moter it cuts everything off and in my case it trips the mains power but may not in your case
I have an O'Keefe & Merritt double oven gas stove. The model
number is 72 7242 23. The upper oven is about the size of a large
microwave and sits above the range burners. The lower (full-size)
oven is below the burner unit and includes a broiler draw below it.
So, when you say, double oven, I wonder if you are just talking about
the main oven with broiler drawer (both of which are below the burner
Mine was a builder-supplied appliance in the new house we purchased in
1986. The upper oven has never performed very well. And,
yes the upper oven can only be used for baking.
I have an instruction manual for it, but it doesn't provide that much
information. Getting parts for it is extremely difficult, since
Tappan is no longer manufacturing this brand. (I've been trying
to locate a flat oven ignitor for the upper oven and can't seem to find
a replacement that's the same 6-1/3" length.) In the 1980s Tappan
apparently purchased O'Keefe & Merritt and marketed this brand for
several years. Models originally manufactured by O'Keefe
& Merritt in the 1930s-1950s are considered collectible antique
