There was a spark and then the power light went out on our 1973 electric cooktop. I had cleaning people in a few days ago who took the burners apart for cleaning. Could something just be loose?

Hi,

Here is a tip that I wrote to give details about why your cooktop will not spark to light the burners..

Cooktop Range Stove spark ignition does not work

heatman101

you need to check the wiring to that burner it appears that there has been a short to the burner

do you see a spark when you hear the click? if you see the spark then YES let it dry and you should be fine.

did you spill liquid on the cooktop? sometimes if you just let it sit for a few days to let it dry out it will fix itself. but if you spilled oil on it it will not fix itself. you have a bad spark module and the only way to fix that is to remove the cookyop fromt he burner box. and find where all the wire go into this usually redish orange box sometimes its blue. but that is your spark module. let me know if you have any more questions

your spark modual got shorted with the liquid you sprayed in there or spilled you can try unplugging it overnight to let it dry. at least 24 hours or you can take the cooktop of and get a hairdryer and dry out the spark modual.or if you wait 24 hours - 3 days and still not dried out you need to replace your spark modual but more than likley give it time it will fix itself.

I don't have a Thermador cooktop but here is ma taught.

Could you unplug the two faulty igniters and see if problem remained

Could you plug one of the faulty igniter at the location of a good one. The goal is to isolate the problem. Is it the igniter or the electronic board.

Faulty ground problem may occur also after an spillover on the stove. In that case, use a cotton swab dipped in scrubbing alcool and clean the spark area on the igniter and the burner.

Good luck

Throw your circuit breaker that leads to this unit for a few seconds, then reset the breaker This unit is very sensitive to power fluctuations.

Hold your finger or thumb on the red light for a few seconds, and you will hear three beeps. This tells you that the lock is off. If the light is not on, do the same and there will be three beeps, and the light will come on, telling you that the lock is back on.

u got gas going to them or dirty vales

We have an older Thermador Gas Cooktop type range. It was working fine until the cleaning crew came in, then all the burner igniters were clicking when turning on a single burner. I solved the problem by cleaning off the igniters. I first of course unplugged the power. Then I took a small wire telcom pic tool to scrape the white and brown deposits from the sides of the igniters. You could probably use something else similiar to do the scraping. I noticed a shiny surface underneath. I then went ahead and scraped and brushed clean the mating surface where the spark travels. I then vacuumed up the mess. My burners all worked great after this. Hope this helps!
