My electric range has power to the control panel, but none of the stovetop or oven elements heat up. Help?
Question:I recently changed the cord on the back from a four-prong to a three-prong to work in an older house. The lights on the control panel and clock work fine.
Answers:
The elements require 240 volts, controls are 120 volt. An outlet for a range provides the 240 volts as two 120 volt legs. The controls use one of the 120 volt legs along with the neutral, which with a 3 wire plug is tied to the ground.
One of the 120 volt legs is working, the other is not, so you have 120 volts for the controls but not the 240 required for the elements. Given this is an older home, do you have fuses? The range circuit requires two fuses, I would bet one of them is blown.
It is possible that you have a problem with the way the new cord is wired or even the outlet could have some problems, but check the fuses first.
Wiring is incorrect. You messed up somewhere there. Look again at what you are doing. You are probably still using the ground wire. That is not in a 3 prong
Check the wire that you exchanged for the three prong. It should be one black or red wire for your hots. Your neutral and ground should be together.
The four-prong plug had two 110v power lines, a neutral return, and a ground wire.
A three-prong plug has two 110v power lines, and a neutral return.
I believe you are missing one of your 110v lines. unplug and rewire the stove.
If the wiring checks out then have a look and make sure the auto timer hasn't been set. Some timers have an "on" timing and an "off" timing.
Fell into that trap myself once.
