Question about Carrier XHB123D X/Y Series Heat/Cool Air Conditioner

1 Answer

Series 100 model no. 58ssb095bc carrier gas fired surnace

The existing inducer fan is making some loud sounds when comming on. The existing heating system is locking out. When testing and jumpering out the blocked vent switch the system comes on. The existing flue serving the existing heating system is open. The system will fire normally for serveral days and lock out again. Are the blocked vent switches only good for sensing only one flue gas failure or should it be replaced. Also could the existing fan induced motor be defective and is not removing all the flue gases causing the blocked vent switch sensor to open and lock down the heating system. I thank you in advance for your attention to this matter.

If it is making noise, the motor may be ready to give out. The pressure switch could be faulty, but it sounds as if you need to replace the vent motor if you can find a replacement. Otherwise you've got to replace the entire vent.

This is a down flow unit. There is no pressure valve on this unit. Here is all the parts on this unit.
1. Manual - reset, when used.
2. Blower and blower motor
3. Relief box also known as a exhaust flue.
4. Gas valve control knob or electric switch, ON/OFF
5. Gas Valve
6. Gas burner
7. Ratting plate
8. Blower door safety switch
9. Blocked vent safeguard tube and switch
10. Gas Manifold
11. Manual limit switch (2)
12.Hot surface ignitor
13. Flame sensor
14. Inducer blower motor
15. Control board with relays and transformer.
That is all the parts. The first thing the heater gets a call from the thermostat to the control board marked W. The board sends 24v to the inducer fan relay which makes and causes the inducer fan to come on now there is a small tube that runs from the inducer fan box to a switch when the switch makes it sends power to the board which proves you have cleared the exhaust flue then the flat surface ignitor starts to glow and then gas valve opens and fires. now if this tube is stopped up the heater will not fire and will lock the unit out. Also if the flue is stopped up with trash it will do the same thing. If you are not familiar with gas heating units you should call a service company out and check out the system there is a lot of things that need to be checked out every heating season as to keep you and your family safe.

Heater check out list for heater failures


Almost all furnaces built after 1978 have intermittant type pilots.
Ca banned them requiring electronic spark or hot surface ignitors, followed by induced draft motors, pressure switches or centrifigal switches that "prove" a induced draft exists, allowing the pilot sequence to commence.
electronic spark type units have a high voltage low amperage spark that is AC. Fire rectifies electricity that passes through it meaning AC becomes DC ! Fire is a terrible conducter however as a result , the DC signal is only milliamps/volts signal strength. the DC prescence is proof a flame exists for pilot, and safe to commence to mainburners.

As long as pressure switches stay closed, safeties and limits stay closed
and the DC signal to the ignition module is not broken, the furnace will run.

The normal sequence of operation is upon a call for heat from the thermostat a 24 volt signal is sent to W white (heat circuit) at the low voltage terminal board on furnace.
from there depending on unit and age the heat circuit may include a circuit board, but it still has the typical limits and safetys reqired for operation
its just not using electromechanical relays to control fan and induced draft motor etc.

for the induced draft to begin ,all limits, safetys in heat circuit must be closed.

induced draft begins and a proving switch, either pressure or centrifigal close allowung the pilot to begin, a spark or hot surface ignitor is energized and a pilot flame established,modern types use flame rectification to prove a flame, older Carrier, Payne,types have a 3 wire switch in the piloyt assembly that is a bi metal that expands and contracts clicking open and shut, allowing pilot or main burners, depending if cold or hot.

pressure switches are attached with tubing to the induced draft wheel housing and sense pressure differential and close upon induced draft running, the orifices that the tube attaches to on induced draft housing often plugs or is restricted causing pressure switch to fail to close, or waver on open and close , open , close, .

if you can run the fan in the on postion , you have both high and low voltage to the furnace.

if you dont have fan control check power, breaker , fuses.

When the thermostat calls for heat sometimes the gas pack works fine and sometimes it doesnt work at all . the inducer motor comes on but the burners dont ignite . what could be the problem ?


Could be the igniter or the thermocouple. The blower has to start first and it does but it will run on endlessly without further action unless the igniter heats the thermocouple to open the gas valve and fire the burner.

Thats a safety.

The unit senses a failure to ignite, so it goes into safety mode keeping the blower running to prevent overheating and fires. And keeping the inducer motor running to prevent the same, as well as raw gas build up inside the unit.

The newer systems are "smarter" and can detect more specific problems and failures. The older ones simply know that the thing didn't light, so they bring on the fans for safety.

Urnace fan of some sort runs all the time - set on automatic


If you have it cleaned twice a year they should be able to find this problem. It is one of two thinkgs. There is a limit switch on the fan at the top (inducer) this may be weak and causing the inducer run frequently. The other is there is another limit switch it is a main limit on the fire wall it is also weak and that is why the main blower is running it is trying to cool that limit.

HEATER MAKING LOUD NOISES


Check the draft inducer motor for any partial blockages or dibri.

I've seen sticks, birds nest particles and pieces of deteriorating fan blades (squirrel cage type fans) cause this.

You might also find that the inducer motors bearing are going.

If its a loud vibrating grinding type noise, I'd suspect bearings or missing pieces of the blades. (unbalanced)
If it's a clanking type noise I'd suspect loose items hitting the fan.

The inducer motor will only operate right before and during burner operation, while the blower motor can operate at any time depending on your setting.

Turning on the heat makes a loud noise then i turn it off and just run the fan no noise


This sounds like an oil burner, which would mean your getting an oil biuld up in the fire chamber when the burner fires up. If it is a gas furnace you need to ajust the air flow.
