What is the difference between the WB13T10045 Igniter and the WB13K21 Igniter? Is there a thermocoupling included in the WB13T10045. Right now I have the WB13K21 and it is lighting up and the gas starts flowing but gas shuts off very soon after.
There is not really any difference between the 2 igniters. Neither igniter has a thermal couple on it. You will want to check the oven safety valve as this would most likely be the cause for the gas to shut off too quickly. It sounds like there is a weak coil on the valve.
My oven screw holding the ignitor broke. Can I use any similar screw or does it have to be a special one used on appliances? The range is a GE profile. I bought a zinc screw 10x32. Will it work or will it melt?
Answer Hello S.M.H.,
I would recommend to use a steel screw because of its' expansion and contraction. A zinc screw may seize and twist off the next time you have to remove it. A stainless steel screw would work great but would be overkill.
My broiler works but the oven doesn't (although the display reads 100). I have limited tools..... can I just replace my igniter or should I really test the various electric points. What igniter model number should I use for my oven model?
You can visually inspect the igniter to see if it is broken but the best way to find out what is wrong is to test the components. Test for 3.2-3.6 volts AC at the gas safety valve with the igniter turned on. If the voltage is there, you have a bad safety valve. If the voltage is low, you have a weak igniter and the igniter will need to be replaced. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
