I've got a 5-year old Tappan gas range. Two of the burners don't ignite, the other two and the oven are fine. What do I need to do to fix the problem? Will buying a new spark module fix it, or is the problem somewhere else?

Re: Tappan gas range burner ignition
Hello paultoledoWelcome to fixya. I'm Huuum and happy to assist you,
You said, You got a 5-year old Tappan gas range. Two of the burners don't
ignite, the other two and the oven are fine. What do you need to do to
fix the problem? Sounds like a yes from where I'm sitting, your right on target, buying a new spark module will fix it.
That sounds like the spark modules. I think you are correct!
Let me know if you need me! Please remember to leave a solved rating! Huum

You will need to look and see if the igniter is glowing a bright red. If it is weak, the oven will not light. Here is the igniter if you need to order it. Also check and make sure your getting 3.2-3.6 volts AC to the valve.
If you don't smell gas, then it is probably electronic ignition and not a pilot light.
But if your oven and none of the range burners light, are you sure you are getting gas to the unit or from the range valve to the burners and oven? Can you light the burners with a match? If you can you can rule out the valve and incoming gas line, and concentrate on the ignitors.
Electric gas igniters sometimes get stuck in one position causing a clicking sound. The clicking sound that you hear is the electric arc that is pulsing from the igniter conductor (wire) to ground (the gas burner). It receives power from the electrical outlet that the stove is plugged into.
Residue from food and sometimes cleaning products may be preventing the igniter from producing a spark (Arc) to the base of the burner. This is a common problem that occurs when the stove has been cleaned or food is allowed to build up. Make sure that the igniter and the burner base are clean and dry. This will help with proper operation. Oven cleaner and a small tooth brush may be used to accomplish this. Another problem with ignition may occur if you have too little (touching) or too much space between the igniter and the base of the burner; it will prevent the burner from igniting. You should only have a little more space than the thickness of a nickel between the burner base and the igniter. A good "blue" arc from the igniter to the burner base is optimal. If this doesn’t work, you may need to replace the electric igniter module. Good luck.
Lets take the oven problem first. Sounds like you have a Hot Surface Ignitor problem. This is the device that glows and lights the burner. You can buy a universal ignitor at most appliance or heating and air conditioning supply houses. Note carefully how the old one is mounted. You may have to make some adjustments to mount the new ignitor, but it MUST be close to the gas burner like the old one! You don't smell gas because the gas valve will not open until the ignitor is hot. All ignitors work with the same voltage, so simply connect the new wires to the old ones.
I'm not certain if you have a standing pilot for the stove top burners or electronic ignition. Remove the top panel to check. If you have a gas pilot, relight it. If electronic ignition, clean the ignitors. If that does not solve the problem you may have to call a technician, as these systems can be complex.
I would suggest looking at how long before the bake burner ignites. If taking longer than 5 minutes before it ignites, then you are looking at a possible bad ignitor. The ignitors just don't last more than 5 yrs with regular use.
Almost always a weak oven igniter. Remove oven floor by removing 2 screws at rear of floor. Remove flame spreader from burner, if it has one. Turn on oven and see if igniter gets red. It's the caged thing on burner tube. If it does but doesn't light gas, replace igniter. UNPLUG UNIT FIRST!! Put dishwashing soap on threads of 2 screws holding igniter in place. This will allow it to come out easier. Do-not use oil. It will make your oven smell like a diesel truck. Remove screws. You will have to remove drawer in front. Underneath you can fin wires from igniter. These will be cut at igniter and connected to igniter with enclosed wire nuts. The 2 wires to igniter go either way.
