Having problems with your Air Conditioners ?

I have 4 header split type air conditioner. Time & again it stops and operation and timer light flash altenately and I have to to turn off the power at the switchboard and turn on again to reset. Sometimes this happens 2 or 3 times a day and other times it operates correctly for days. I have cleaned the filters and checked the electrical connections. 2 years ago I had a tech from Fujitsu who came and checked everything and could not find any faults. I am getting a bit concerned as this is occur

Answers :

\015\012On the days it happens alot is there a temperature corolation??? Are these days warmer or colder then the days it runs all of the time???
\015\012Have you checked the charge on the unit???
\015\012Would there be any power surges or fluctuations???
\015\012It would seem also that this may be caused by a faulty sensor... but you will have many sensors between the five pieces of equipment that it could be and it may take it failing completely for you to be able to pin down exactly which it is...
\015\012You may be able to narrow it down by shutting off one head at a time and seeing if it still locks out... but that would take many days to make sure that you have found the fault...
\015\012Unfortunately there are probably no good answers to be had any time soon here and not without a ton of detective work...

Intertherm Electric Furnace in mobile home Model# MRAC 2317 SN - 79JE0501 Question: The blower stays running all the time. I have to turn the main breaker off to turn the blower off. The unit is heating when it is running. I have replaced the thermostat about 3 years ago in the summer when I had a AC problem. Would the fan switch on the furnace possibly be the problem? It has an auto & on position on the switch. It clicks when you switch to the on position but does not click when you put i

Orginial system in the rest of my house is fine. We need some advice Thanks Danny England

Dirty sock syndrome. It's caused by high humidity in the duct system and/or home. This could be the result of an oversized system and/or improperly sized ductwork. I would advise getting technician certified by NATE in AIR DISTRIBUTION to come and ... Goodman CLQ36AR49 Air Conditioner

My goodman heat pump has frozen up 3-4 times already this summer. It is a dual system 10 seer (i believe are the terms). Every time someone comes out they can't figure it out because the system is running fine by the time that they come. Two years ago the blower or activator was replaced (maybe the replacement part isn't so good?) The unit is 9 years old. Last year a guy charged it and about a month ago when it was checked the freon was only a little low. I'm SO tired of this issue. Any ideas

After system has been running 10-15 minutes, the discharge air temp should be 18-22 degrees colder than the air being sucked in. If the air is more than 22 degrees colder then the problem is with air flow. Check filters, blower speed, make sure all ... Air Conditioners

I have a lin-stat thermostat. Electric baseboard heaters. There are only a set button and up and down arrows. Turned the breakers off in the spring. Turned them on today and the thermostats will not turn on. Screen is blank. Tried holding set button down, no luck. Neither did pushing the up/down arrows Need help to turn them on. Thank you. Bought house 4 years ago and no issues last year. Also no instruction booklets.

I just had my AC unit checked as part of a duct cleaning package. The final step was the technician checking the freon levels at my outside unit. He attached gauges and told me that my unit is 2lbs low. (The unit is just about two years old). He then hooked up a can of R22, opened the can reaevoir, turned it upside down, opened the handle to the gauges and turned them back and forth for literally about a 5 second time frame. Does this sound like my unit received a two pound fill of freon? Or did

If he only added R-22 for 5 seconds, then no, it did not take 2 lbs. Even if this was possible, the R-22 being upside down, (meaning it was charged in a liquid state), it would flood the compressor and more than likely cause damage. Now, it does not ... Air Conditioners

A/C worked fine last year. Turned it on for the first time this year and the outside unit does not come on. The inside unit fan works just fine. I checked the circut breaker and turned on and off.

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 have a 18000btu LG mini split heat pump installed about 1 year ago in vacation home. In heat mode the unit cycles on and off when room temp is within 2-3 degrees of set point. Cycle on time varies between 35 to 60 seconds (sometimes more). The off time is 2-3 minutes. During this time, I check inside temp with accurate digital themometer mounted at the air intake of the unit and the temp does not change, assume because unit does not run long enough. When I put temp set point more than 3 d

AC for my RV won't even turn on, fan, nothing. I have had a few problems this year with it blowing the breaker on my home, but the last time I ran it from my home a month or so ago, it worked fine. Today when I went to turn it on, the fan won't even run let alone the AC. I would agree that the filters need to be cleaned, but not to even turn on, even for 2 seconds? What would you think it is and how would I find out?

You are saying it causes the breaker to trip?( or was past tense?) sounds like there is a short somewhere. that's why nothing comes on ... Coleman Mach III Air Conditioner

Ruud Silhouette II furnace: comes on and runs for as long as it wants, then turns off. Sometimes turns off at pre-set temp, other times just when it wants. May turn on again, behave well for several cycles, or for 20 minutes. When I get too cold, I go out, downstairs, and thump it near the fan. Starts right up, runs for as long as it chooses. Nearly least energy-efficient kind, v. frustrating. Had trouble-shooter out a few years ago, couldn't find anything. An intermittent short?

My fan and heater work fine, but today I turned on my air conditioner for the first time this year.

I have a newer Bryant 340aav furnace that came w/a new house I had built not even 3 years ago. The house was completed at the end of November & come the next spring it was discovered the installation crew never put freon into the a/c. Fast forward to 2 years after that (March of 2012) I went to turn on my a/c to discover it was just blowing lukewarm air. Had the crew come out again & put in almost 2 lbs of freon. The technician insisted he checked for leaks & found none so I paid him his service

I have a Bryant split system AC that is 18 years old. We have been away all summer (2 1/2 months), during which time the thermostat was set to 80°F. We live in SE Virginia and summer temps are 80's or 90's. We arrived home less than a week ago and turned the thermostat down to 72°F (at all times - we have small children and I am pregnant, so we need the house to be cool 24/7). The system was working fine until this afternoon, when I noticed the house was warming up. The temp had reached 76°

I have an electric furnace and heat pump that will at times blow only cold air during the heating season. I have checked the filter and don't believe that to be a problem. I usually have the temperature set to 74 degrees. When the outdoor temp. is extremely cold the axillary heat indicator will be on and still no heat. I can turn the heat pump off by switching to emergency heat and will get some heat from that but not as warm as I think it should be and even that will at times only blow cool

Turned it on for the first time this year. After a few minutes it would stop working but all the light indicators are still on. I made sure that the energy saver is off, that is is getting the full 220 volts, and presst the test and reset buttons on the plug. No results. Unplugged it for a few minutes and tried again. Same deal -- would start and then stop working after a few minutes but also noticed a burned electrical smell. Could it be the capacitor or something?

Yes, it could very well be a burned capacitor or a burned wire from over heating, Best advice is to unplug the unit and do not attempt to use it, until it is repaired.To find an authorized service in your area, click on the link below. ... Friedrich Compact Programmable CP24N30 Air Conditioner
