OK so fan works in FAN On but nothing in heat,No elements or blower?
correct fan works perfectly fine when i turn it on but when place on auto and temperature drops below SET sometimes it works both fan and heat sometimes it doesnt
How about right now.If you turn to heat will it come on?
no it is not working right now
OK Lets eliminate thermostat first. Go to furnace and lets twist red and white thermostat wires together and see if heat comes on.
so i had the thermostat off to see if i could find a part number to order a new one and when you said to try tightened the caps i put it back on and heater and blower started working without touching anything and this is my issue sometimes it works and sometimes it doesnt
and to be honest with you i think its the thermostat cuz it makes a click sound and i just have the feeling that sometimes it doesnt send the msg to turn heater on because when i put it on the ON it will turn on right away and when i put it on auto sometimes it works sometimes it doesnt
Lets forget thermostat right now, Jump it at the furnace.
ok im at the furnace
Twist red and white together.If heat comes on disconnect. Then repeat 3 or 4 times.If it comes on every time you will know thermostat is the problem
Did it come on?
twist red and white cables together?
The red and white that are in tan wire nuts.Loosen wire nuts and connect them together.Heat should come on
connect all of it together or just the big ones
Doesn't matter, you can leave all together or separate they just go to thermostat
ok and that should turn on the heater and blower?
ok they are connected and its not on yet
OK we have eliminate thermostat from being the problem, Leave the wires together and check between the white and gray wires at contactor coil to see if we are getting 24 volts ac.
im sorry but i dont know where to find the contactor can you send a picture of where it is
Remove the screws and take this panel off.Then send me a clear picture and I will show you where to check. Note you can kill power while removing panel so you do not touch anything hot wit the panel.Then remember to turn power back on before testing for voltage
Ok you have a sequencer rather than a contactor, Back up and take me a clear pic of the wiring on this sequencer
Excellent. Leave the red and white jumped outside of furnace.Turn power back on and see if we get 24v between this blue and white at sequencer coil.
i only have this you think it is going to work out?
That one will not read 24v we will need one like this.
you can get an inexpensive one at Walmart for about 15 bucks
ok got it tested them and it doesnt reas anything follow it check the breaker and it doesnt read anything checked the cables after the breaker and nothing
OK sounds like breaker is bad if no voltage from breaker
how do you explain that sometimes it works and sometimes it doesnt?
If you have no power it will not work.I am going to open to other experts who may be able to help from here.

ok so i checked the breaker at the main breaker and it was off im sorry i checked again at the breaker and i have power now its just turning heating on and off but the blower will not respond!
I am about to leave office tonight.I will leave open so other experts can help.Will check on the s tatus tomorrow.
i feel like you may know the answer to my problem i checked the white and blue cable that you told me and it doesnt have any power to it
Sorry but I have to leave.If we have 24v out of thermostat we have to have a break somewhere in this circuit if no 24v ta that sequencer.Will check on you tomorrow.
