Do you have a new style control box? What color is the box?
Ok, Do you have a flashing yellow light? or just the purple light when first plugged in?
When you replaced the thermocouple, it is very important that the wire end is completely installed all the way to the very end of the ceramic thermocouple cover, then the whole assembly is sticking ONE inch over the end of the firepot. Can you check this?
That is too far. You need to have it placed one inch only over the lip. Only the end of the thermcouple can be getting hot, otherwise the voltage is too low. The voltage is generated from the difference in temperature on the thermocouple, and if the whole two inches gets hot you will not get enough millivolts.
I need to look up the specs but I think you should be getting more than 15 MV
Try reversing the leads on the thermocouple connections.
I can do the call if that doesn't work. How old is the stove?
Did you try reversing the leads? That may be the problem.
Yes, the two leads coming from the thermocouple, try reversing when they are connected.
They can just wear out over time, or your control box may have gone bad. Its hard to say, or it may have just need pushed back a little :).
Glad that worked, it happened to me once and I finally just tried reversing the leads and it worked.
Did you have any follow up Questions? Let me know if the red light comes on and it continues to run.
