Furnace wont start when thermostat sends signal

I have an Beckett oil furnace and a digital thermostat. When the temp in the house drops below the temp set on thermostat, the thermostat send a signal to the furnace but the furnace does not start. When I press the restart button on the furnace it starts, heats the home to the set temp and then shuts down but it won't restart once the temp in the house drops again. What could be the problem?

Bad primary control (the box with the reset button), maybe your thermostat but unlikely. Try the Primary Control first. How old is your burner?

I have a Rheem Classic Super Quiet 80 gas furnace (for heat). The fan stops when the "heat" turns on.


Any time I ever had trouble,first thing to suspect is the thermostat.
They lose contact sometimes and sometimes you tap the face and they work til next glitch.
If the thermostat has some years on it,go ahead and replace it.
Can't you just leave the heat and fan in auto? That would be best,I think. don-ohio

Our thermastat won't let us reset the temp. it says its locked, we have no idea what that means or how to fix it, or even it that's the problem. our furnace thermostat.


What type of thermostat do you have?
You can call the company that installed it to get the over ride password or how to reset the thermostat so you can control the temperature

We have royal red furnace to heat our home.The fan dose not stop.


Details.......does the furnace function normally otherwise? Might just be a stuck fan switch. Make sure the thermostat hasn't been set on Fan ON setting or summer air circ. on older furnaces.
Find the fan switch and tap it and see if fan quits. If it does,fan switch is bad.probably. Always make sure your air circ. filter(return air to furnace) is replaced every 3 mo. or so,too. don-ohio (:^)

My thermostat is set on 68 degrees and it shows room temperature is 68, but the furnace still kickson, Honeywell said it has a 1 degree difference. so what's the problem then?


Yes there is a one degree tolerance, in fact my heater just kicked on and it is set to 67 and the inside temperature reads 67. It is also a Honeywell.

My oil furnance is running but when it reches temperature it shuts off and will not come back on until we bleed the lines


You have a small leak on the suction side of the pump between the tank and the pump. when this happens the pump looses prime each time the furnace shuts down and when the furnace tries to fire up again the saftey device trips before the oil gets to the burner.

Electric Furnace stopped running


You have one of two problems. Either the capacitor for the motor has failed or the motor has failed. I would turn off the power to the unit and see if you can locate the capacitor and remove it. An ac supply or electrical supply house can match up the capacitor. This is relatively inexpensive. Otherwise you will need a new motor.

Why can't I lower my honeywell 8500 below 67 on cool?


With a two story house you have to be aware that cold air flows downwards so any cold air coming from an ac unit will flow downstairs( normally down the stairway) so unless you can close off the down stairs then the up stairs unit will be cooling downstairs as well. Ac units have a thermostat located in the air intake and it cools until the cold air has risen to that point. In effect the space above the ac unit will be hotter than the floor. Knowing how they work ,you can see that the upstairs unit will never reach the set temperature because the cold air is continually heating from the house and will never get to the top thermostat.
So your solutions are
1-- fit controls that restrict the cold air from leaving the upper floor (Doors)
2--don't run the upper ac unit unless you are living up there (waste of money
)3 place an ac in each upper room and keep the room door closed
