Question

I have an Amana range (3 yrs. old) I just replaced the spark module for the burners and now I am having a problem with the oven. Sometimes the ceramic (?) glow coil will work and sometimes it won't. I have so far been able to get it to work by jiggling it??? Does it need replacing or could it just be a loose connection?
Thank you,
Dan

Hello: Dan

Based on the information you have posted, if I am reading it correctly, I would suggest you check for a loose electrical connection at every point you had to disconnect and reconnect.

Most likely there is a poor ground to or at the spark module. Could be one at the ovens selector switch too.

If your referring to wiggling the glow coil to get it to lite up, check there also for a loose electrical connection.

Sometimes working in one area effects another componet. This may be the case with the wiring of that appliances particular electrical system.

Basically you'll need to retrace your steps for the replacement part and work backwards looking for what may be loose or incorrectly reinstalled or connected.

Question

Tom,
Thanks for your reply. If I understand you correctly, the spark module for the burners is related to the oven ignitor? Or are you saying I may have disturbed something else when I replaced the spark module? It seems to me if the oven ignitor was bad it simply would not work at all. Is this a correct assumption?
Again, Thank you,
Dan

Hi Danzio

The key point is there may be a connection between the parts electrically. Most stove and oven appliances <what's usually called a free standing range> there isn't any common connections between the two systems. Your model may be different. You have to check that. Difficult for me to say exactly unless I was there in person.

The other key point was the loose connection possibility. Check and recheck each connection point. That also includes the glow coils connection. May be in some way connected to the electrical source at the spark module, for the glow coil.

The spark module may be the first part connected thru the fuse, which could mean it gets the voltage first, then passes it onwards to the thermostat, etc. Not likely but possible.

The usual power source for the ovens glow coil is the thermostat. The gas valves power is usually thru the fuse and passed onwards to the thermostat. The other wire on the gas valve is connected to the thermostat.

The ovens thermostat has interconnections with any optional selections...Timed Bake...Keep Warm...Timer...etc. Any of those connections and power sources could be suspect.

You'll need to locate where the current is and at what time based on the selections. I suggest setting everything to manual for the test. Even that isn't a guarantee power is where it is suppose to be even when set in manual.

You'll need to apply your problem solving skills to trace down the location of the power failure. Consider the case of the glow coils failure to work at all times.

Could be a coincidence that you made a none related fix and it's simply a defective coil...

Regards &
Good Luck

Tom,
Thank you for your reply. It never fails to amaze me the wealth of information available on the internet and how so many good folks (like you) are willing to share their knowledge and give of their time.
I am likely going to replace the ignitor coil since I have been unable to troubleshoot the source of the problem elsewhere.
Again, many thanks,
Dan
