I replaced the thermocouple in my gas furnace and it is running longer than it did before but it still shut off so what is the problem?
It could be a couple of things:
1. Wha is the condition of the pilot light? Does it have a yellow or white color to it? If so it will need to be cleaned. It could also be buring with to much pressure and blowing itself out.
2. What is the thermocouple connected to? If it is a silver color box (and not directly the gas valve) it could be weak and need repllacing.
3. If it is connected to the gas valve, that could be your problem as well, but it is an expensive replacment item.
4. Is there a down draft coming from the chimney? Air blowing down the chimney that does not have a cap on it can also cause the pilot to blow out.

What is wrong if you turn the thermostat to off but the furnace is still running?
When you say the furnace is still running, I take that to mean the fan and not the actual flame portion of the furnace. If this is correct, you either have a fan relay that is sticking closed or your tstat is bad. == == == == There may be a very slight time delay the the thermostat before turning off the furnace, but if you are sure that you have turned the thermostat off and the fire continues to burn, you have a serious problem. Have it checked out. The gas valve may be sticking in the open position. Regards
