My Crusader Carrier horizontal furnace was installed in January of
1990 and has worked well. I have a problem when we turn the thermostat
down at night the furnace will fail to activate when we turn the
thermostat up un the morninng or it will fire up and bring the house
to the temp but will not fire again when the temp falls. I replaced
the thermostat and that fixed the problem for last winter. but the
same problem is occuring now. I turn the heat off and then back on at
the thermostat and the fiurnace fires up and runs fine. I know the
fist solution is to not turn the furnace down but I would like your
help fixing this problem.
Are you using analog or digital thermostat? If it' an old analog type,
how about replacing it with a programmable digital. Let the program do
the job of turning the thing up/down. Buy a good one like Honeywell.
common problem, replace the thermostat again,
home depot has dozens of very inexpensive models to choose from
im sure replacing several thermostats will be cheaper than
calling a competent technician to come out and perform a rotuine check and
cleaning , which BTW when was that last done ?????????
p.s. i think i know what your problem is , and its not a tstat
you need a service call from a competent tech

There are a number of safety features in your furnace related to it
starting up. I suspect one of them is acting up and the problem has
nothing to do with your thermostat. Unless you're exceptionally handy
and have some eletrical background your best bet is to just call a
good service guy.
well first of all I am A real HVAC tech thank you, I was asking how many
conductors where running to the stat but you had to be a smart ass I guess
you have to be smart somewhere. I was tiring to help the guy with his
problem so if you don't have anything helpful to add then please keep it to
yourself. I would use a DVOM to diagnose the problem but its hard to do over
A "Real HVAC Tech!" Omg! Let me bow to you! ROFL
The thought of the day; call you local HVAC tech, tell him / her to bring
out a Honeywell S86 ignitor [common on that furnace] and flame sensor. Get
out your wallat and pay the HVAC tech to diagnose and complete the repair.
Enjoy your heater!
