Wont cut out,triggers overload valve and keeps running


The points are stuck on the pressure regulator not allowing it to kick out and cycle as it should. Make sure the unit is unplugged and totally discharged before making any repairs to the pressure switch...i hope this helps.

the unit has a hi pressure safty switch on it, probally has a red push button on top. when the water slows down or stops the hi pressure trips to shut unit down to prevent compressor damage, the switch does not reset it self, find it in the outdoor unit and reset it, let me know. thanks wally.

What are the carrier 8000ts led error codes?


They are listed inside the front panel of the main unit.

LED CODE

EACH OF THE FOLLOWING STATUS CODES IS A TWO DIGIT NUMBER WITH THE FIRST

DIGIT DETERMINED BY THE NUMBER OF SHORT FLASHES AND THE SECOND DIGIT BY

THE NUMBER OF LONG FLASHES.

STATUS

11 NO PREVIOUS CODE - Stored status code is erased automatically after 72

hours. On RED LED boards stored status codes can also be erased when power

(115 VAC or 24 VAC) to control is interrupted.

12 BLOWER ON AFTER POWER UP (115 VAC or 24 VAC) -Blower runs for 90

seconds, if unit is powered up during a call for heat (R-W closed) or R-W opens

during blower on-delay.

13 LIMIT CIRCUIT LOCKOUT - Lockout occurs if the limit or flame rollout switch is

open longer than 3 minutes.

- Control will auto reset after three hours. - Refer to #33.

14 IGNITION LOCKOUT - Control will auto-reset after three hours. Refer to #34.

21 GAS HEATING LOCKOUT - Control will NOT auto reset.

Check for: - Mis-wired gas valve -Defective control (valve relay)

22 ABNORMAL FLAME-PROVING SIGNAL - Flame is proved while gas valve is

de-energized. Inducer will run until fault is cleared. Check for:

- Leaky gas valve - Stuck-open gas valve

23 PRESSURE SWITCH DID NOT OPEN Check for:

- Obstructed pressure tubing. - Pressure switch stuck closed.

24 SECONDARY VOLTAGE FUSE IS OPEN Check for:

- Short circuit in secondary voltage (24VAC) wiring.

31 PRESSURE SWITCH DID NOT CLOSE OR REOPENED - If open longer than

five minutes, inducer shuts off for 15 minutes before retry. Check for:

- Excessive wind - Proper vent sizing - Defective inducer motor

- Low inducer voltage (115VAC) - Defective pressure switch

- Inadequate combustion air supply - Restricted vent

- Disconnected or obstructed pressure tubing

- Low inlet gas pressure (if LGPS used)

If it opens during blower on-delay period, blower will come on for the selected

blower off-delay.

33 LIMIT CIRCUIT FAULT - Indicates a limit, or flame rollout is open. Blower will

run for 4 minutes or until open switch remakes whichever is longer. If open

longer than 3 minutes, code changes to lockout #13. If open less than 3 minutes

status code #33 continues to flash until blower shuts off. Flame rollout switch

requires manual reset. Check for: - Restricted vent

- Proper vent sizing - Loose blower wheel - Excessive wind

- Dirty filter or restricted duct system.

- Defective blower motor or capacitor. - Defective switch or connections.

- Inadequate combustion air supply (Flame Roll-out Switch open).

34 IGNITION PROVING FAILURE - Control will try three more times before lockout

#14 occurs. If flame signal lost during blower on-delay period, blower will come

on for the selected blower off-delay. Check for: - Control ground continuity

- Flame sensor must not be grounded

- Oxide buildup on flame sensor (clean with fine steel wool).

- Proper flame sense microamps (.5 microamps D.C. min., 4.0 - 6.0 nominal).

- Gas valve defective or gas valve turned off - Manual valve shut-off

- Defective Hot Surface Ignitor

- Low inlet gas pressure

- Inadequate flame carryover or rough ignition

- Green/Yellow wire MUST be connected to furnace sheet metal

45 CONTROL CIRCUITRY LOCKOUT Auto-reset after one hour lockout due to;

- Gas valve relay stuck open - Flame sense circuit failure

- Software check error

Reset power to clear lockout. Replace control if status code repeats.

If status code recall is needed, briefly remove then reconnect one main limit wire to display

stored status code. On RED LED boards do not remove power or blower door before initiating

status code recall. After one status code recall is completed component test will occur.

Our frigidaire window a/c unit (model faa067p7a) does not seem to be operating properly. There is no condensate forming anywhere (beneath the coils is dry and no evidence of water and there is no water...


It sounds like your unit is low on freon or the compressor is not kicking in. If the compressor kicks in you can hear it turn the unit on fan only or turn the thermostat off then turn the unit to demand cool you should hear a hum even vibration when the unit kicks in. If there is no audible hum ect... your compressor is probably not kicking in. The selector switch the temp switch the capacitor for the compressor or the compressor its self could be bad. good luck if you need to know how to test any of the above let us know

Unit shut down for 24 to 36 hrs whith power to it/ lights inside still worked


By shut down I'm assuming you mean the compressor does not come on. Does your unit use dials or electronic controls ? Try raising the dial to max and see if compressor kicks in - otherwise unplug the fridge for a few minutes and plug it back in to see if it resets - you either have a shot compressor or a faulty control board (faulty control board being more common) followed by stuck defrost timer.

Ok, it can be two things.
  1. The outside unit needs to be washed with a water hose to rinse any dirt and debris that can cause a restriction in airflow over the outdoor coils. If they are allowed to get dirty, they can cause the compressor to overheat and shut down on thermal lockout.
  2. The unit has a small refrigerant leak and the unit doesn't have sufficient refrigerant for the system to run thus causing the compressor to shut down on thermal lockout. The problem with this one is that generally the inside coil will freeze up and you will notice that.
Compressors generally won't come on at all if they are bad. You can have a compressor go bad and still be running, but it won't cool at all. A bad install can cause a compressor to fail as well. Generally if the compressor fails within the first 10 years, you can bet it's because it was a poor install. This means that a proper vacuum wasn't pulled on the unit before initial start-up. Hope this helps.

Carrier home ac system


sounds like your contactor is stuck closed.This is the part that high voltage connects to and lets power through to the compressor and condenser fan motor when you get a call for cooling.If you go to pull it out,kill the power outside AND at the furnace.
