SOURCE: Ruud heat pump outside unit trips circuit breaker

Check your wiring between the contactor and compressor for a short to ground, or check the compressor windings for short to ground.
With the Tstat off, the contactor should be open so the only way for the compressor to be trying to do anything is if the 110 volts from the unbroken side are traveling through the compressor to ground. Since 110v is not enough to run it, the overload is kicking it out, cooling off, and repeating the cycle. When you kick on the Tstat, the contactor is supplying voltage directly to ground without going through the resistence of the compressor windings and kicking the breaker.
Post back and let me know what you find.

SOURCE: Blower in Attic not running

inside unit has fan control relay , either on control board or can be separate ,except for the 24 volt transformer and the t-stat the units operate separately concentrate totally on the inside unit this is where the problem lies

You have clean the blower unit , may be its dirty then . and then check the blower resistor unit for malfunction.

Amana PTAC PTH093E Fan runs at single speed only regardless of setting-auto/low/high Hot or cool air is coming out so compressor/heat coil is working. Reset unit and replaced fan motor-no change.


I've replaced many Amanda control boards. They have micro relays attached to the board. These relays are about a half inch by 1 inch in size, and control line voltage to the compressor and blower motor, and give up quite often. Its probably the board if its a digital controlled board. If it has manual, turn to select, type knob, it will be in that fan section knob. Hope this helps!

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.

Motherboard,It just went, burnt, for no reason,I sent it


Usually a "fried" motherboard will result from a faulty AC adapter / power supply. If the voltage it provides is too high, kiss the motherboard good bye! Most adapters output voltages around 18-19 volts at around 90 watts. If the adapter malfunctions, the voltages do not have to go much above the range to cause havoc.

If the repair shop did not FIRST check the voltage of the AC adapter before plugging it into a new motherboard, I would seriously consider a new repair shop!

GMPN 100-4 furnace. Blower motor runs when not calling for heat.


The board is bad. The unit thinks a flame is present, so it tells the blower to come on. Replace the board.

Inside blower not starting every time


You have a voltage bleed somewhere or a short, whatever you want to call it. Do you have a control board on this unit where the relays are integrated into it or do you have the old type where the relay is separate? Anyway, you need to take a meter and take voltage readings to the motor when it's acting up and when it's running right. I have had the same problem with a Goodman unit before and it turned out to be the tstat! What I would do is remove the cover off the tstat and take a small jumper wire and touch the r terminal to the y terminal. If the motor starts right up, you know it's the tstat. If you have the same problem, then the only thing it can be is a low voltage short to the unit from the tstat, bad control board if you have one, or a bad relay. But if the unit is working fine in heat, it's probably not the relay. I hope this helps.

Heater no longer works on auto fan, only manual fan


When you call for fan in auto ensure your getting 24 volts at pin on control board, if it is not energizing then there is a problem with the relay.. Before you change out the expensive control board, try the therm..

Overheating? burnt oil smell


There is a seal between the compressor and the motor that in failed condition will leak oil into motor windings causing burnt oil smell. Some hitachi compressors suffered from failed valves or head gasket causing extra heat but not oil smell. These compressors also have a thermobreaker built into the windings that when failed will prevent motor from starting or would start and run for only a few moments then open. This part is not replaceable. enjoy

Goodman Heat/Air unit Model # A49-20 Serial # 9909502720


It sounds like the blower motor has burnt up.(the one inside) The unit running for a few minutes then shutting off, is due to the high pressure/temperature safeties. When you removed the panels, did you notice any fan running?

Heater problem model PHK 080-1


THE BURNING SMELL IS NORMAL. BEFORE HEATING SEASON OPEN ALL DOORS AND TURN THE HEAT UP AND LET RUN TILL ALL DUST IS BURNT OFF. IF BLOWER IS NOT COMMING ON NOW. THERE ARE 2 TIME DELAY RELAYS, AND ANOTHER RELAY FOR "FAN ONLY OPERATION". ALWAYS MAKE SURE THEY ARE NOT THE PROBLEM BEFORE REPLACING AN EXPENSIVE MOTOR.
