The "Oven On" Light is intermittently Lighted (aka "on") even though the Oven is Off.

The oven coils are still cold. It happens for minutes or hours at a time, then stops for hours. It started a couple months ago, then stopped for a couple months.

I can get the light to temporarily turn off if I put the Oven in Auto-Self-Clean mode.

Advice, please?

July 1 Edit: Sometimes when the light isn't properly off, now it flashes.

I don't use my oven much; but I did today.

Once I turned it on, I heard a click every second while it heated up. But the ding never came to signal it was preheated. So I looked inside, and the upper (Broil) coils were red even though I hadn't set the oven to Broil (I set it to 525, which always only activates the lower coils).

When I'm done cooking I'll let it cool then determine if the lower coils are even working.

In any case, there's a problem with oven beyond the Light.

10 August 2017 Edit: And now the coils all remain cold no matter what I set the oven to. My landlord says he thinks he'll just buy me a new oven.
