Having problems with your Air Conditioners ?

I have a unit that it is blowing out cold air when have it on heat. I have had issues in the past where the heat stop working. I had the part fixed and now i have no heat again. Where i live it is 11 degrees and it not planning to get warmer no time soon. I need some advise asap because i had a tech come out to look at it and they are stating that the gas valve is receiving the correct amount of voltage but it is not opening and suspecting a cracked heat exchanger which all this sounds famil


Answers :

Check power goes to heating coil by a volt metre. I think, it's better to calla repairman to repair/replace the heating sensor or heating element.

My central heater is not blowing hot air, I am having to turn the thermostat on and off. I have the thermostat to 70, and the heater will blow hot air and then it will just circulate the air in the house, therefore bringing the temperature down. I looked at the unit and noticed that when the thermocople (heating element) goes red, the gas valve makes clicking and the flames come and then go out very fast. I noticed lots of clicking in coming from the gas valve. help please

Robert Shaw 2000 wiper gas valve quit working on a ruud, 50 ga. heater being used for floor heat. The spark looks weak. The pilot looks weak as well. All the pins are clean looking and wires appear to be attacked well. The unit was purchased in 2003, run for a couple of months before we figured out the application wouldn't work. We moved it to another location were it has worked fine for two seasons. Pilot and burner tubes are clear. Oriface in pilot tude is tough to blow through, but it is tiny

Older Sunbeam Heat Force 85,000 Btu, LP salamander heater with a spark igniter, small sealed circuit board, asco red hat gas valve and temperature switch. The temp switch is an Elmwood L295 1/2" diam. surface mounted ceramic, 2-terminal sensor. The Asco valve is a Red Hat normally closed gas 110v, 10.1 watt valve. On/Off control is a toggle switch. The problem: I turn the unit on....fan starts, gas valve opens, spark igniter light flame....all good for 15-20 seconds. Then the gas valve shut


Hi,The problem is that whatever is sensing the flame is not telling the control that the flame is on...Not sure what you have on that unit, but I suspect that it is a photocell that sees the light and then tells the board that there is fl ... Air Conditioners

I have votage coming from the control board "PV" to my electronic valve. My question is do I have to change the entire electronic valve or should check some other things first.

Lost power, gas from the gas valve was still flowing into the heat exchanger even tho the piiolet was not lit..... should I replace the thermo coupling or the gas valve or both


Sounds like the valve stuck open. I'd do both just cause you are there. The thermocouple is not the much of an additional expense. No gas should ever flow with the power off. ... Air Conditioners

I have a 1985 Bryant central air Furnace model 395BAW048095 with a White Rogers 36E gas valve. The flue is metal and there is a fan within the furnace to create a vacume at the base of the flue pipe conection that turns on when a call for heat comes from the thermostat at startup to ignition. The spark fires but no gas is released by the valve for the pilot to lite. Added information: The blower fan is set to continually run, I replaced the pressure switch (306621) and the limit switch (HH12ZB18

Hi , I have a Electronic pilot lighting system on my RUUD package unit. The pilot light flame keeps blowing out or is not working properly. I removed the panel to look and see what was wrong. I could not see any faults. The sparker worked just fine, the gas line tubing was fine no blockages( took it off to inspect it) every thing looked good. Worked fine for the last couple of weeks and now it will not ignite the pilot light to light the rest of the propane gas to heat the house. I tested the fl


Sounds like you have checked most things. A pilot will go out if it is dirty, if the gas valve is not holding or if the senser is dirty or bad. Remove the pilot and clean out the small orifice inside. Check all electrical connections, clean the senso ... Ruud UBHC Air Conditioner

Our whirlpool water heater is not heating. My husband replaced the thermocoupler and it still doesn't work. We have had it for 8-9 months. Whirlpool is sending a new gas valve. We are reading that this will continue to happen even with the new parts. Is there a universal gas valve that we could replace it with that will work or should we consider just purchasing a different hot water heater? The model number is BFG1F4034T3NOV.

I smell an odor possibly electrical but I was unsure and had the gas company come and check. The gas company serviceman states the gas connections are good, nos gas smell in any areas of the house. The unit is putting out heat at the correct temperature but the smell of a burning odor worries me. What should I check to verify an electrical problem?

My 1985 Kenmore furnace is not starting. It has a Honeywell DSI. There is a nice spark going on, but it seems no gas is coming in. (The water heater is connected to the same gas line, and it fires-up allright) Looks like the honeywell valve does not allow the gas to pass thru. Any hints?


You need tools. You need to check if there is any open sensors not allowing electrical current to travel back to the gas valve and open up like normal. Turn the furnace on c ... Air Conditioners

The gas valve on my Honeywell Glow Worm Space Saver Mark II boiler has failed. The part number on the valve is V8600A 1024 2. It is a 24v valve.

Brivis Wombat 92 heating unit - I am having trouble getting the pilot light to stay lit. The gas is on, the igniter is sparking and the pilot light ignites but when I gently release the red gas valve after 60 seconds as prescribed in instructions the pilot light flame extinguishes itself. Have tried venting the gas line to get rid of oxygen and this isn't helping. Any ideas?

A 2 month old Goodman GMH95 natural gas furnace has been working properly until tonight. Now it starts up properly, but after 30 seconds (and right when the cirulator fan kicks on) it shuts the gas valve stopping the flame. LED light flashes 8 times, which is not an option on the trouble shooting guide. Unit will retry every few minutes and cycles this way over and over. It appears the control module is not receiving the gas flame detection signal. What do we need to do?


Goodman's control boards are very sensitive as well as the connections to the gas valves. Check the wires and make sure they are snug and tight. With it being only 2 months old, I doubt the board is bad or the flame sensor(unless it is a used syste ... Air Conditioners
