Having problems with your Air Conditioners ?

Hi All, I have a carrier reverse cycle airconditioning unit and about a week ago the digital thermostat blanked out. I spoke to an aircon repair tech and he suggested that the fuse is blown at the air handler and suggested that I can probably replace the fuse myself. My question is where is this fuse located in the carrier units, do I have to open panels or is it in a box like a fuse box in a car. I have no issues checking the fuse if I know where to find it LOL, The model of the unit is

Answers :

It will be inside the unit main panel. Turn main power off and remove the main front panel. The fuse will be located on or near the fan control board. Typically they are a flat agc type fuse. 3-5 amps. The problem will be that if the fuse is blown -there is a reason for it. They don;t just wear out and blow. Look for frayed wires around the outside unit and in the thermostat to make sure you dont have a short. Otherwise, you will just blow the fuse you replace.

When I turn my electric a/c to heater it makes a repeat tac sound quite loud. An a/c tech opened the metal box on left side where the fuse is located and said that the board and relay needs to be replaced. My a/c heating unit is an American Standard made by Trane model TWV036B140A1. What do you think it might be the problem? What are the technical name or numbers of the parts the a/c tech is referring to? Where he or I can buy it and for how much? What is the guarantee? Thanks. Tommy reply2t

It sounds like the tech was referring to the blower relay. The blower relay on this unit originally had a small circuit board mounted to it. It's only purpose was to allow for delay off-time of the blower at shutdown. In other words, once the command ... American Standard Air Conditioners

Goodman a/c j41 fan not running, turned off and on at fuse box, took a look at the box next to a/c unit and opened the box on the wall and pulled the plug and pulled the plastic panel off, there is no fuses. So i put back together and turned the a/c unit on, now at thermostat the snowflake is no longer flashing, some cold air coming out of vents, but outside a/c unit fan still does not run.

First you need to disconnect all power. Try spinning the fan blade, if it spins freely, then try moving the shaft from side to side to see if there's any side play. If not then the bearings are OK. If there seems to be some drag when your spinning th ... Goodman CKL42AR42 Air Conditioner

Our inside unit Coleman EB20B (outside unit Goodman GKL 49-1) keeps blowing the in-line 3 amp thermostat fuse. We've rewired the wires in the wall, rewired the contactor wires, and the contactor was broken so we replaced it. We're still blowing the fuse. Could we have reversed the thermostat wires at the contactor? Or could the short be in the Blend Air box-this box is coupled to the thermostat wires? Thanks Ken Rohm

Cental air unit stopped working, I replaced the capacitor which had blown apart, but the unit does not restart. It works when I push in and hold the button on what I believe is the relay where the power comes into the panel of the unit. Is there another fuse or reset button that needs to be reset within the unit. Any suggestions? The model # is AC1BN036-A and it's from about 1995.

Gas furnance would only operate for about 3-5 minutes then turn off. Replaced gas valve on furance for a Rudd comerical A/C 4 ton unit model UKKA-A048JK10E. Now the blower fan turns on but the igniator and gas does not come on as before. LED light (flashes 5 times) on board indicates flame roll out switch is open. Need manual to locate roll out switch, does it have a reset button or does it need to be replaced?

The rollout switches will be located at the ends of the burner assembly and will have a manual reset. they must be manually reset to ensure that the problem has been corrected. Most units will go into a soft lockout for a time and eventually a hard l ... Ruud UAKA042 Air Conditioner

Compressor on Ruud Unit UAMA-042JAZ and its fan won't run. Electric comany said low voltage circuitboard problem. Suggested replacing the fuse on the circuitboard. I could not find a fuse, where would it be loacated?

The units has what you call a contactor which is actually a relay but it does not look like a relay. You can get a none conducting material to depress it. and the compressor should run and the fan. Be very careful since that contactor has exposed par ... Ruud UBHC Air Conditioner

Hi, you do have a power problem, that's for sure.If the indoor unit has a non-fused box, and condenser also, it would have to be at the main breaker. That's the only power source you have that supplies power to everything is the main breaker. If you ... Air Conditioners

I have outdoor Goodman compressing unit, model #cple24-1c. The breaker tripped and I was told to take out the connector located in the box by the unit and reset the breaker. The breaker did not trip again. I was told to replace the electrical whip because we had alot of rain recently. Is this right?

No, the electrical whip should be able to handle all weather, moisture, and even immersion. The only reason to replace a whip is if it has suffered some kind of physical damage. I recomend keeping an eye on it and if it trips again, have a pro come ... Goodman Air Conditioners

My Goodman Mfg AC unit is blowing fuses on the control board inside the blower/air handler unit. This fuse supplies 24V to the outside compressor unit. Originally, there was a 3 A fuse in it. I replaced it with a 5 A fuse that lasted for a year. Now it has blown. I suspect that the solenoid actuator coil on the outside compressor unit is becoming lossy and drawing more amperage in the hot weather and my solution is to replace that component. Does that sound right?

Planning on replacing my Federal Pacific circuit box. It is a 24 breaker box. I just checked it to find that it is rated to handle up to 125 amps. Few days ago, an electrician checked the box and suggested a 100 amp 20/40 Siemen box. Until today, I did not catch the amp difference between my old box and what he has suggested. I have a call into him. Doesn't make sense to me to go to a lesser rated box. If anything, I would think that a replacement should be a larger amp box, ie 150 or 200 amp.

You do not need to replace the main circuit breaker with less rating, it may trip during peak loads due to lesser current carrying capacity. If you are planning to replace the main circuit breaker with higher rating, you must verify first if the main ... Air Conditioners
