    If your filter is plugged that could have been the problem. Do not put that filter back in. Replace it asap. Try unlpugging the furnace for 10 secs and plug it in again. See if that resets the furnace. Let me know if that worked.

One of your limit switches has tripped. You will find 2 wires terminating to a small disk about the size of a dime or penny. Between those wires is a small button, depress firmly to reset it. You will have anywhere from 2 to 5 of these and you need to reset all of them just in case. If that doesn't seem to be the issue, then it is probably a power failure of some sort. Is the unit getting power? Is the transformer working and the output rating will be 24 volts? If it is not getting power, check you power cord and make sure it is in good condition, check the switch that is located under the blower door, check for a 3 amp fuse on the control board. That just about covers most common problems with gas furnaces.

Why is my furnace filter dirty after 3 days

depends on what you are calling dirty which is relative to each person
Are they so dirty they are clogged or do they just have dust on them
IF they are just dusty then that is normal and it is being pulled from inside the house
If you have a pet door that will cause a lot of dust
The only other way is if there is a hole in the attic or your return air somewhere

1 Answer

I have a Carrier model # 58MXA080-F-15112. I think my furnace is 30 plus years old. it isn't heating properly. The blower turns on and sometimes the flames come on, but sometimes they don't. As...

A 13 code means the furnace cycled on limit more than three times consecutively and is in a lockout for 3 hours. A 14 is ignition lockout. An ignitor does not intermittently quit working. I'm the service mgr at our shop, and I know that particular furnace model has a service bulletin out on bad secondary heat exchangers. If your lucky the filter is dirty, or the furnace condensate trap or drain is clogged. Most likely the secondary heat exchanger is plugged up and isn't allowing the pressure switch to make. Or the furnace is overheating due to it not being able to properly vent hot gas. Which would explain the high limit lockouts. Call an authorized carrier dealer so you can take advantage of the free heat exchangers and the $300 labor credit. You can also call an authorized Bryant dealer to perform the work for you. Only an authorized dealer can rectify this problem because the Bryant corp requires testing and paperwork in order to get your free parts and labor credit.
Good luck.

Furnace blowing warm air, ac overheats

Sounds like it is tripping on it's high pressure switch. This could be caused by a dirty condenser coil, overcharge of refrigerant, or non condensables in the system ( air most likely). I would get a second opinion from a repuatable company, sounds like he's trying to rip you off.

I have central heat and air system, my problem is when in heat it runs for 10-15 min. turns off and about 20 seconds later starts back up. It shts off before hiting its tstat. temp.

If this is a gas furnace and you have a cooling coil on top then you could have a dirty coil. Also a dirty air filter can do this. I have also found dirty blower wheels. The gas furnaces have a high limit to prevent the heat exchanger from over heating. Another possibility is always a possibillity; however, 99% of the time I find an air flow issue.

Bryant 340mav036080 limit switch reset time

The primary limit switch in your furnace is an "automatic reset" switch, and should reset itself within a few minutes.

It is a safety device designed to prevent your furnace from overheating. If the furnace does get too hot, the limit switch opens and the burners turn off. The blower should continue to run until the furnace cools down again. The limit switch should then reset itself (usually less than five minutes).

If it will not reset, try tapping on the switch with a screwdriver or other tool. This will often un-stick it. If this does not work, the switch has failed and must be replaced.

A furnace will overheat for many reasons, but the most common are a dirty air filter (should be changed every 1-3 months), or a dirty evaporator coil (only if you also have central air). Make sure everything is clean and all your vents are open to help avoid this problem in the future!

There are other limit switches in the furnace as well, which are "manual reset". They will not reset unless the little red button on them is pressed. If one of these switches opens, it is best to call a contractor to evaluate your furnace, as an unsafe condition may exist.

Bryant-Carrier Furnace Fan Stays On

I suspect a bad fan relay or bad fan control. Maybe the longer the control or relay is in the on position the more chance of it sticking on.

Code #33 on Bryant 355MAV 90i Furnace

'Limit or flame rollout switch is open'. In my case, the flame rollout switch had tripped due to an overheating? I had to push the button between the wire leads to reset the switch. Then when I turned the power back on, the furnace started up like normal.

Why did the switch overheat and trip? My current theory is that there was a rubber grommet around a pipe near the switch that had slid down and was no longer sealing the furnace?
