Hi. I have a LG heat pump/air conditioner. A split system with 2 indoor units. Model LMN095HV and LMN125HV. After a power failure by our local power company, I am getting a CH 05 error code. I have turned off th power to the units and waited several minutes and turned it back on with no luck. I know the code means poor or no communication with the outside unite. And I am getting the same code on both inside units. an you help? Thanks, Peter C [email protected]

I live in central fl We have a older tempstar electric heating/cooling unit there is power to the indoor part and the heat works. I have power to the inside breaker for the cooling but no power to the outside unit breaker. theres no power to the outside unit at all.


The outdoor unit should have it's own 220 volt breaker, and on the wall near the outdoor unit should be a disconnect box, some disconnects have breakers, others have just a disconnect bar, and behind the metal plate are fuses.\015\012I would c ... Air Conditioners

Still will not start and continues to display error E1 This unit was purchased in June 2007.

I found the Bryant furnace 395cav048090 calling for heat but not operational. I shut off power to the unit and switched power back on and the unit started its ignition sequence. With power on the blower starts as a result of thermostat calling for heat from the unit and after a minute goes on to second phase of ignition with exhaust blower motor initiated. During this phase gas is being brought to the burner that you can smell however burner does not ignite gas. Unit continued with this opera


If you do not see a bright light before the gas releases, your ignitor is probably out. If you disconnect, you should measure ohms from the two ignitor leads. If you do not measure any, it is open and will not work. You will usually see a mark of whi ... Bryant Air Conditioners

Not a GE unit. I charged unit with refrigerant and powered up unit. After running for @ a minute it shut off, having no power light at all. I found a set of wires reversed that were going to the outdoor unit. after fixing the wires i can't get the unit to come back on. The breaker is not popped and I assume there is some kind of fuse or overload that I have to manually reset or replace. It is a chinese (i think) made unit Air Control


Since most of these units, come precharged for line sets up to 125' in some models, the fact that you charged it, concerns me.

AMCOR 24,000 BTU split system. Worked fine two years, then today it had no power. Checked circuit breaker, it had popped. Reset CB and went to inside unit - would not turn on or off with remote or hard button. Checked wiring with an electrical tester, and wires to outside unit hot, as well as inside unit. No flashing codes, nothing. Unit won't turn on,even with power. Is there a fuse somewhere in the inner unit or outer unit?


I had this same problem. I disconnected the thermostat wire out side at the condenser and reconnected it and it started working. A couple days later it blew the breaker again this time I found the bus where the L1, L2. GR wire connect at the condense ... AmcorAire UCHW-H24AF2 Split System Air Conditioner

I want to find the transformer for the 36 volt inside unit. Is it in the inside unit or outside unit .I have no power to the inside unit however the outside unit has power,and the inside unit appears to be 36 volt


It's a 24v transformer. Your indoor unit houses the transformer for the outdoor unit. The outdoor has a low voltage (24v) supply running to it to push in the contactor for the outdoor unit to run. If your air handler inside has no power then it will ... Comfort-Aire HMC36AT-1 Air Conditioner

AC unit Amcoraire AOS241HX @ startup i have power to the L1, L2 power inlet terminals to the outdoor unit but no power to the lines going up to the indoor unit. What can I do to correct problem?


These should be seperate circuits so lets forget the condensing unit for a moment. It should not come on because it gets the control voltage for the contactor from the indoor unit. Check your circuit board for a 3 or 5 amp fuse and make sure it hasnt ... AmcorAire UCHW-H24AF2 Split System Air Conditioner

I have an Amana Model GUC-C 90 Hi-efficiency furnace that we installed in 1992. It has a central air unit as well. On Friday we tried to turn the air on and nothing will work. I have replaced switches in the air unit in the past but this time there is no clicking, I can't turn the circulation fan on for the unit, the heater unit will not turn on. I have power at the breaker, and on the unit itself there is a on/off switch with a round screw in fuse, that fuse is good and I have power there.

I have a model # faa065p7a A/C The power cord burned out with some sparks by the test and reset part. Called frigidaire and they said you could not replace the power cord and had to buy a new unit. This AC is not very old and worked fine. Is this true because I see that power cords are for sale and never heard of the whole unit going bad from the power cord. Did the electronics fry or was I talking to the wrong person? They were not very helpful and just said to buy a new air conditioner.

I have a Carrier Heat Pump model FK4CNF003. I noted that the thermostat wasn't working (no power) so I checked the usual suspects...in bound power etc. before I pulled the top housing off the interior unit. I noted lots of wires on a circuit board in the upper right corner of the unit which seems to route power and signals to/from the thermostat. Looking closely, I noted that the 5 amp fuse was blown so I put in another 5amp fuse and it blew as well. Given the fuse is blown, and I'm assuming


You should be able to trace the short to a specific componant on the board itself. the 5amp fuse protects the board itself. trace the circuitry back from the imput side. you should have a multimeter that has a audio alarm that will tell you which cir ... Air Conditioners

I have a 2005 Pilgram 27 foot 5th wheel. My Duo Therm AC unit makes a ticking sound from the ac unit itself when it's not running. Shutting off the Duo Therm analog thermostat does not stop the ticking sound coming from the AC unit, nor does cutting the AC breaker (20 amp), nor cutting the ac power to the entire RV.
