I need a little central heating help, question?

[Jyruiz]

When I turn on the heater, after about 10 to 15 minutes, the heat goes off, but the fan stays on till we turn it off because then the house does not get warm enough to have the thermostat shut off the system.
Any idea what it could be?

[WestTNRiverRat]

Gas or electric heat?

[Jyruiz]

Gas or electric heat?
Guess I should have gave that info as well, sorry. It is gas.

[WestTNRiverRat]

Standing pilot light or electronic ignition?

[Jyruiz]

If the thermostat is not reaching temp, why does the heat shut off? Or is that your question?
Thats my question.

[Jyruiz]

Standing pilot light or electronic ignition?
I don't know, how can I tell?
Took a pic of this,

Try changing the filter

[Jyruiz]

Try changing the filter
Filters are always changed and currently not dirty.

[Rvr Swpr]

Try turning the thermostat way up ,like 90.Have switched over to heat from cooling?

Thanks, I have already tried that.

[Jyruiz]

Can you make the heat come back on right away by switching it off and back on?
Yes.

[riverroyal]

or something in the board.Switch it cooling,you have a/c?Run it in cooling,see if it shuts off then also.That will eliminate and gas or heating issues

[rsoscia]

is the furnace up in the attic

[Jyruiz]

is the furnace up in the attic
Yes.

[riverroyal]

or in cal?Do you have a out side condenser for the a/c.Looks almost like a heat pump

[Jyruiz]

or something in the board.Switch it cooling,you have a/c?Run it in cooling,see if it shuts off then also.That will eliminate and gas or heating issues
It works fine when using the AC.

[rsoscia]

Whats the brand name ? It could be one of the heaters that was recalled

[Jyruiz]

Yes.

[riverroyal]

Bad relay, bad circuit board. Don't bother looking any further.
if its a heatpump could be a bad reversing valve.Which is also a electrical issue which will require a service call

[WestTNRiverRat]

A standing pilot light is a small flame that is always lit. It lights the gas when the thermostat opens the gas valve.
Electronic ignition uses a spark device to light the gas when the thermostat turns the valve on. Just like a gas grill.
Have you verified at the unit that the gas is actually lighting when the thermostat is turned up ?

[Jyruiz]

Whats the brand name ? It could be one of the heaters that was recalled
Its a Premier.

[riverroyal]

Yes.
bad board or relay.Sounds like the gas valve is shutting off for some reason.When they 'fail' or have issues they go to normally closed to turn off the gas.You can put a jumper wire to by pass the relay for the part.But without being there its tough to do from here

[rsoscia]

That furnace was recalled for burning peoples house down...look it up online.
That furnace has to be replaced... no contractor can fix it they have to shut the gas off and replace the heater... better to be safe then sorry...

All Premiers? This unit was installed in 91.

[rsoscia]

not only preimers there were alot others... call me

[WestTNRiverRat]

Could be the flame rod. That tells the control board that the burners have lit after the gas valve has been turned on by the thermostat. If it fails to sense a flame it will cause the gas valve to turn back off. That is a safety device that prevents your house from filling up with gas. They will get carbon deposits on them over time and malfunction. You can remove it and hit it with some sandpaper and that will take care of the problem.
On a side note, if you don't know if you have a standing pilot light or electronic ignition, I wouldn't recommend trying to repair it.
Just thinking about the safety of you and your family.

Have it inspected for cracks/holes in the heat exchanger, go to the web sight and see if it is on the recall list.......

[Luckie Stiff]

All Premiers? This unit was installed in 91.
Yep, according to this website http://www.cpsc.gov/cpscpub/prerel/prhtml01/01189.html
ALL heaters manufactured between 1983 and 1994

[rsoscia]

Preimer went out of business right after the recall

[rsoscia]

Yep bad design ... the metal rods above the burners break , after years of service , then fall out of the furnace and presto your attic is on fire

[hairysituation]

Its the limit switch

[Jyruiz]

Yep, according to this website http://www.cpsc.gov/cpscpub/prerel/prhtml01/01189.html

Yup, it is on there, model number matches. Thanks for the link.

[Jyruiz]

So what are my options?

[rsoscia]

What is the condition of the A/C unit... you dont have to replace the A/C ... Ive replace the heater only several times... let me know if your need a quote

[Jyruiz]

Yes, please give me a quote for the replacement of the heater.

[rsoscia]

call me right now check your pms

[Havasu1986]

So what are my options?
I got nothing here. Any questions about fire sprinklers. I'm your guy. :D

[Luckie Stiff]

So what are my options?
Unfortunately your only real option is to replace the heater, and if your A/C was installed in 91 as well, you might as well upgrade it to a higher SEER rated unit. I just did mine last summer, went with a Carrier Infinity, using 410A refrigerant, cost me roughly 6K with all the bells and whistles.

[Jyruiz]

Unfortunately your only real option is to replace the heater, and if your A/C was installed in 91 as well, you might as well upgrade it to a higher SEER rated unit. I just did mine last summer, went to a SEER 14 Amana, right at $4K for everything.
The AC unit was replaced in 97 I think, so I don't know if I want to replace that just yet.

[Luckie Stiff]

I just looked at my paperwork, the Amana would have been $4K, I went with Carrier, $5873 installed, new heater, condensor, compressor, thermostat.

[Rvr Swpr]

Thanks, I have already tried that.
You are alot of help in the electronic dept. appreciate your info.

[Jyruiz]

Thanks everybody for the help, looks like I got to get this thing replaced.

[Rexone]

Mine is a Premier too and on the list. foooooooooooooock . I sent you a PM...

[Brewzed]

With a furnace of that age, you need a mirror and flashlight and look for cracks in the heat exchanger. You have to pull the burners to get to the heat exchanger, so take a 5 gallon bucket with you so you can dump the crap from the burners and hit them with a wire brush. If you find cracks, unplug it and get a new one ASAP, you'll go to bed and never wake up. Your coil might be dirty and the squirrel cage (fan) might be dirty, that may decrease the airlow and the furnace will overheat and shut itself down too. You can remove the fan and use an air compressor to clean the blades.
You said your filter was clean, so I'd also check the roof vent and make sure it is on properly and clean. If it's not venting properly, it will also shut it down.
those are a few things you can do real quick to check before calling a tech out.

Who thought opening a thread could cost you $5,000?? :eek:
