I have a Carrier 58STA gas furnace that is four years old. The problem
is when the thermostat calls for heat the inducer fan kicks on then
the igniter will glow, the burner ignites and the flame will go out in
about three seconds. The unit will restart the process and ignite
normal and run until the thermostat turns it off. This happens every
time. I had the local hvac company that installed it here two weeks
ago and they performed a fall service stating this would clear it up.
I had them back a week later and they said they had to clean the flame
sensor. Well it didn't fix the problem so I replaced the flame sensor
to still have the same problem. I not trying to play HVAC tech but I
really want to fix the problem. I paid the company both times and they
want to charge me for a service call to try to come out and fix it on
the third time. Any direction would be helpful , Thanks in advance.

Uhhhh..... Call them again, and let them know it's still not fixed. You
might NOT want to tell them you had your hands in it. If that doesn't work,
try another company, as you'll be paying someone anyway.

I agree, call them back. Tell them it is doing the exact same thing.
I suspect a cause here, the sequence of operation thing. An Annual
Service would eliminate a majority of causality here and is a great
first step. Now they need to spend some time with it and catch it in
failure, if not redo the Annual Service.

Most companies do want your business so give them a chance to make it
right. This isn't a walking in a room and turning a light switch on
and light bulb going out situtaion (for us in the hvac field, and
what you may have read on this board, the customer is always telling
us, "the heat doesn't work so it it must be the thermostat.") You
wouldn't replace the light switch but rather the light bulb, right?

I am not sure how the company you are working with is set up, but
asking for the service manager to share your, "this is the 3rd trip"
concern would not meet with apathy, condemnation or anger. It will
get their attention and remember, we are in a business here and want
to maintain your business relationship.


My cockiness does want you to post what they find, as I said, I do
suspect a cause and want to know if I am indeed right. :-)

You "suspect a cause?" (the sequence of operation thing??)

Im pretty sure that's going to earn you a Darwin of the month award.
Besides.........everyone knows its the thermostat.

Just keep replacing parts and you'll get it. Also, I'd definetly
replace the thermostat, it's always the thermostat.
