To turn on a furnace without a thermostat, locate the furnace switch on or near the unit. Flip the switch to the "on" position to start the furnace. Keep in mind that without a thermostat, you won't be able to control the temperature or set a programmed schedule for the furnace to operate.
Check the wiring connections to the thermostat to ensure they are secure and correctly connected. Make sure the thermostat settings are set correctly for the furnace to turn on at the desired temperature. If issues persist, consult a professional technician to diagnose any underlying problems with the furnace.
If the thermostat has failed it will need replaced.
I had mine replaced and the cost of the thermostat and housing was $48.67 without the cost of labor.
$500 without the thermostat $750 with Thermostat $1000 with all hoses replaced
Every Electrical Furnace run by Electrical Current. Without electricity we can't use any type electric furnace. Sometechnical knowledge must be required for maintenance of electric furnace. Spare parts availability like Heating elements/resistance wire, Thermostat/Temperature controller (maybe Digital or Blind controller, Contactor, Insulators etc.
You can buy a new thermostat at Home Depot or Lowe's, or even your local hardware store. They will cost around $20 (low end) for one without the central air options. You can order online too: http://www.thermostatshop.com/honeywell.shtml
A thermostat that is stuck in the closed position is a very common cause of overheating. A new thermostat should be installed every time the coolant is changed.
I am guessing by the question you want either of these stats to be able to start the furnace, without using a relay. As long as you are using the same control power supply for both the answer is yes. Use the same connections on both if that is what you are trying to do.
What type of system do you have? Heat pump? With or without supplemental electric strip heat? Warm air furnace? Need to know in order to help.
We just had the whole trane system installed. It is the same specs you are asking about. It also has a new furnace that is high efficiency as well as new thermostat that is digital. We paid $7,800 without the $1500 tax credit. $6,300 total.
with potatoes....OBVIOUSLY
