Out of curiosity, what type of timer is it? Is it just a thermal time delay relay, or something more involved like a 555 timer IC?

If it's a 555, then one should check the capacitor in the circuit.

Can you even get it apart to see the electronics? Never tried......

If you can take a pic of the circuit, I'd be happy to take a stab at guessing the bad component. 555 circuits are really simple, using a cap and a resistor for timing. Even if the 555 was fried, they're like 20 cents each.....
