I have an amana dryer. The heat stopped. My knee jerk reaction i bought a new heater element board (included the therms on the board). While the board instructions did not show how to wire the blue wire but did show the black and orange. I switched the wires the way of the old way and the instructions way. Neither way gave heat.

I tested the 4 therms and 3 of the 4 tested good down to 0 for residtsnce. Part number AP4070513 did not. I bought a new one but it does show resistsnce either, so im guessing its not suppose to?

My questions.
1. What else should i test? Timer?
2. How is the blue wire connected w the black and orange?

Thanks

...so i pulled the top cover off and the orange wire going into the timer was burnt and the term marked "H" that it plugs into was a little melted and loose. I have to assume ill have to buy another timer?

What would have caused this?

(I would prefer not to have a house fire if something else is causing this issue!!)

Here are your parts
Parts for Amana LED20AW - AppliancePartsPros.com

If there is a lose connection, dirty connection or a poorly crimped connector, the electricity sees this as a resistance so when current passes through it, it heats up. This further degrades the connection so more heat and so on and so on till the connection fails.
Could even be that the contacts in the timer pitted and resulted in overheating.

I could not find a wiring diagram for the unit but the H designation is probably for heater so this circuit has a lot of current flowing through it.

I would replace the time4.
Also check the wire if it is damaged you will have to cut it back till you get to nice clean copper and then put a new high current connector on it.

Denman - Appliance Parts Pros (from your link) doesn't have the Timer so I had to go else where to purchase it. (Part in the Mail as we speak...)

Since the Wire is like the exact length, I'll have to replace the whole thing so I can't cut it back and recrimp it.

So, besides age of the connection, what else could cause this wire to overheat and burn? Nothing, just age?

(Scarry that it didn't pop the fuse and or something. The only way I would have become privy to it would be a fire in the basement!!)

No it was not just age.
The connection probably had a problem from day one, it just took a while for it to get bad enough to fail.
