Circuit Board needs to be replace but there are none available. According to the service technician, the problem with the board is the capacitor. Would it be wise to pull out the board and have the capacitor replaced by an electronic shop.

I've never tried that, but a good electronic shop might be able to do that for you; however, it's a risk. \015\012You can also try to contact the manufacturer for a list of their recognized service providers. It's possible the board is availabl ... Samsung Air Conditioners

I have a 10 year old Mitsubishi mxz 325v Multi unit airconditioner that is on the blink. The local service company has been trying to fix it since August and even with the assistance ? of Mitsubishi Tech Support they still are not confident they know what the problem is. So far the following parts have been replaced after dicussion and even an attendance by a Mitsubishi Technician from Tech Support.

Sadly this is a poor service without a proper sincere logical advice. To spend $2500 for a 10 year old set is surely too bad , as they have finally almost constructed a new set except the body/condensers.\015\012In the first place ... Mitsubishi Air Conditioners

My coleman Evcon model DGATO70BDC 1994 starts up and then locks out. The pilot lights and then furnace runs for maybe 2-5 minutes and all that is still running is the air chamber fan. I am thinking of just replacing all parts that could be responsible the problem. There's not much there as probably you know. There is no circuit board just basic electronic ignition,relays thermo senors and etc.. Any help would greatly be appreciated. James

Does your furnace have an air flow sensor? Blowing out the lowest tube will sometimes clear it and allow your furnace to operate. Lack of differential pressure across the burner will cause a lockout. ... Air Conditioners

I have a Sta Rite Max E Therm pool heater and when I start the unit, the fan kicks on but the heater never does. After 45 seconds or so, I get a " Service Heater" light. The circuit board had leds for limit switch, pressure switch, air sensors, etc, but none are lit. The ignition contol module has a blinking red led which the manual says is a "ignition lockout" issue. What is an ignition lockout? Do I need to replace the HSI Ignitor? Or could it be something other than ignitor? Thanks

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

Blower fan stays running. Fan relay attached to small circuit board (coil tabs [timer?]). Capacitor on small circuit board had ''fallen out'' of ic board. Tried to get replacement board, and was sold just a standard relay - told that relay alone replaced the previous relay -and- circuit board configuration (?). Problem still exists (no change). Also changed thermostat just to eliminate as a possible cause, but seems like problem must be in the fan relay area. Question about the wires attache

We have a GE Zoneline Heat / Cool Model 2800 (with Heat Pump Model 3800). The blower works but no heat. The A/C works fine. My brother works for Marcone Appliance parts. He removed the housing to the control board, and suddenly the heat started working. It stopping the next day. We replace the control board, but no go...it still won't heat.

I have a whining sound coming from my Air Conditioner in every mode except Fan. I cleaned the back part of the the unit with a duster and the sound continues. I also could duplicate the problem after turning off the unit for about 10 seconds and then turning it back on. Does a part need replacing?

I am assuming this is a window unit. That whining sound probably is the compressor itself. Not much you can do about it but wait till she goes on out and then replace it. They do make a product that can be added to the compressor called Gemline 88 oi ... Air Conditioners

I have a 98 Sunnybrook w/Dometic Furnace-A/C thermostat control. Just the other day, the furnace would keep running and it got very hot in the trailer until I could shut it off. The thermostat was set kind of low, but we needed to keep a little heat on in case we got a freeze. Do I need to replace the control unit which is electronic to correct the problem? I am assuming the thermostat went bad, but am also assuming it is a part of the control unit?! Thanks for your help. Dave

Control board I've got a Bryant Plus-90 furnace, model starts w/ 350MAV. The status code LED on the control board does not come on. Is this a problem with the control board, or is the issue somewhere else? How do I diagnose the problem? If it is the control board, what is the part number that I need? I've found part number 325878-751 that says it works for most model numbers that start with 350MAV. The word "Most" worries me. I can't find the part number on the current board.

Hello, check to see if the board is receiving 120 volts at the L1 and neutral terminals, if you are then the board will need to be replaced, if you are not getting power then trace the wirimg back to where the voltage stops, for example could be a ba ... Air Conditioners

What areas should I check and how to check them or what to look for? If you could help this would be great.

The first thing that needs to be checked before more parts get damaged is the secondary or control voltage from the transformer. with the system off this should read 25 to 27 volts a.c. on average. low voltage has several possible causes, if you do n ... Ruud UBHC Air Conditioner

Evaporator coil needs to be replace again. Installed w new manufactured home; 09/2005. Replaced 05/30/08. Needs to be replaced again 09/17/09. All due to leaks. Freon was added. Currently has small leak; estimated life is 5 to 90 days. Warranty for part good til 09/2010, but local original installer Weirich Air refuse to replace free of labor charge of Aprox $650.00. Nor will company Nordyne pay for labor. I also feel that Weirich/Nordyne should reinburse me for previous $809.74 labor & service

Blower motor my air conditioning goes off as soon as it goes on I have a service contract with my local oil company and my repair man said I need a Bryant blower motor 8539DL 51923EEOS I have been told the part is not available because the unit is to old and they recommend replacing my furnace and air conditoner for over $15,000 I am hoping I can buy the replacement motor somewhere so I can save for the future replacement of my units Is this part available anywhere?

YES!! A universal replacement is readily available for around 200$ or so and the labor for the installation should be about the same. Sometimes it's hard to tell the Tech's and the Sales apart....GL! ... Bryant Air Conditioners

I have a Carrier 58DX080CC Forced air furnace that is leaking water onto the floor, but otherwise works perfectly. A service guy told me I need a new Coil, but it probably wouldn't pay to repair it, and that I should replace it. His quote to replace was about $6K. I found the part, Z7-58DX080CC-91CW at United parts supply for $890. The unit was manufactured in 1988 and is 90% efficient. What should I do? Buy the part and hire somebody to fix it? Buy a new one?

Hi,If you are running a high efficiency forced air furnace then check the\015\012drain hose and make sure it isn't blocked or crimped. These furnaces\015\012tend to take a lot of humidity out of the combustion air (air from\015\012outside ... Air Conditioners

I cannot adjust the fan speed. it only runs on one speed. i already replaced the p.c. control board part # 309901501 and the display control board part # 309901601.this did not solve the problem. any ideas?

My heat pump will not come on in HEAT or A/C. I thought I might have a simple defrost control board problem, but still no go after replacing the board and the defrost relay. I checked the pressure switch and it is not tripped. I've checked all the circuit breakers and they, too, are all set. I've checked the outside unit using the "test" switch inside on the start relay and the unit will come on, but won't stay running on it's own. When I select HEAT, I wait the necessary five minutes for the un

I have a domestic rear a/c that is just a year old. It clicks and changes from heating to cooling and then shuts off. After replacing to control boards we are told that is probably a coach wiring problem. My question is. "could it be a ground problem related to be replaced a/c?

That is a very good place to start because there may be a wire grounding causing the unit to shut off after changing over to cooling mode. It's what one faulty wire can cause, so check your wiring first. ... Dometic Rooftop RV Air Conditioner

Same here Code 46. Had to replace the mother board last year which seemed to fix a similar problem (but code 61 at that time) - condensor tries to start but kicks off several times then code 46 displayed. Need another new circuit board or is it really a thermistor problem?

It could be suction pipe thermistor or the mother board again but before replacing them it may be just shortage of gas because it will trigger either or both code 46 and 61 as well. ... LG Art Cool LA181CNW Split System Air Conditioner
