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.

I changed the water pump and head gaskets and thermostat. Still overheated. I just took the thermostat out and it's running fine. Who knows!!
Your thermostat or condenser is wired wrong on the control side. Usually there is a terminal inside your furnace that has the same connection colors (Y, W, R, G, C) as your thermostat. It should be connected color to color to the thermostat with the 2 wires from the condenser wired to Y and C.
Sounds like a limit is tripping, removing 24vac from "R" when it opens and restoring it after cooling down. Your description needs significant refining before a remote diagnosis could be possible however. lc
i have a 1999 ford escort zx2 and its running hot, changed out the thermostat thermostat cooling sensor, checked the fan and it works, the temperature gauge in side the car still showing hot, let thecar set over night and the gauge still shows hot, what else could be wrong
sounds like you installed new thermostat upside down if that's not the problem, you have wrong or faulty new thermostat to test thermostat out of vehicle, place in pot of boiling water and watch to see if thermostat opens
air block in heater hose most likely bleed it
Wrong thermostat? Wrong installation procedure?
Is there a flame in the furnace. Precisely where is this air coming from and how strong is it?
There is either a problem with the downstairs thermostat, or the wiring from that thermostat to the unit. First check the batteries in the thermostat. Yes the digital ones have batteries. :-) Next, if that doesn;t fix it, try switching your two thermostats. Be careful to wire them exactly as they were before. If your heat now works downstairs and not upstairs, replace the thermostat. If the problem remains unchanged and you still have heat up and not down - check your thermostat wiring. The voltage is low so a simple voltmeter can be used to confirm continuity from the end where it goes into the furnace to the end where it connects to the thermostat. If the wire checks out and the problem is not the thermostat, then call a licnesed professinal - youhave bigger problems.
Because it's in park.
probably its wrong thermostat and it doesnt open. take it out and run car without it
either faulty thermostat not opening soon enuff, or wrong temperature thermostat still not opening soon enuff
