Having problems with your Air Conditioners ?
NO Heat When I put My Thermostat on The Heat mode, The blower comes on but without heat.
I'm assuming it's an electic unit. Check the fuses to the heater which can be seperate in an older air handler. If the fuses are good, then it's probable that the sequencer is bad or the fan relay switch is bad. It is also possibe that the heat side of the thermostat is bad. You can check this by removing the thermostat exposing the tstat wires and terminals. Take a small wire and jump from the RC/RH terminal over to the W terminal. If the heat comes on, then it's the thermostat. Hope this helps!

Thermostat setting I just bought a new house and I have a heat pump-we live in North Carolina. The name on the thermostat is Braeburn and it is a multi-stage 2 heat/ l cool digital thermostat. We have it set at 68 and when the blower first comes on it blows warm air-however then it switches to cool air. And sometimes cool air comes out first. We have set both stages to 68 and it is in the heat mode. Should the 1st and 2nd setting be different?
What i would do is see if the outside unit is working at all. when you first turn it on the air was warm due to the fact that the temperature inside was cooler than the set point. when it get within 2 degrees ... Weather King 12AJA6001AH Air Conditioner
I have an intertherm electric furnace FEH-A020, with multispeed blower installed when A/C added. My problem is blower operation. at the end of the cooling season with fan set to auto operation the fan ran continuously. Now that I've turned the unit back on for heat the blower will only function with the switch in the on position (continuous operation), in auto mode the heating elements come on with the signal from the thermostat (Honeywell CT3400), but the fan does not. I checked the fan relay p

The blower is on but the heat is not coming out. After leaving as is it start coming out then after the house is warm and U decide to turn it down again blower is on but heat is not coming out. Sometimes it can take up to 8hrs before the heat starts coming out. The heat is perfectly fine when it starts coming out. Another thing is when we adjust the heat it the blower is on but the heat is not coming out holding the temperature at 77 degrees seems to be the sweet spot. Thermostat appears to be o

I have installed a UPM model THM101B thermostat on my Intertherm model E3EB-015H electric furnace. I wanted the feature of turning the blower "ON" without the heating elements. I picked up the green 12v for the fan relay. Once the power is restored the furnace comes on even though the temp setting is low and the only way I can turn the furnace off is by disconnecting the green fan relay wire? The jumper has been properly set in the new thermostat for electric furnace operation.Right now I feel t

My outdoor heat will not operate. It is a Carrier 38YRA042330, with a Carrier Thermidistat thermostat and a Carrier Air Handler 40FFKB005300. I have an H5 error code on the thermostat will I put it in Heat mode and raise the setting to call for heating. I changed the air filter on the air handler when I realized the heat pump was not operating. The air filter was pretty dirty. The system will operate in aux/emerg heat mode, with the fan in Auto or On mode, and will maintain the thermostat
You need to go oside and look for a red reset button on the unit. you tripped the high ressure switch when you let your filter get that dirty. go check on this and when your done if it still is not working then ask me more. ... Carrier Air Conditioners
I have a split system sanyo heat pump model # kmh0922. The evap. fan will not come on when called for in fan mode. When i put it to heat the indoor fan will also not come on. The compressor runs but the reversing valve seems to stay in the cooling mode. When it is put into cooling the indoor fan goes off after 15 seconds and will not come back on. (The condenser fan and compressor seem to act normal in cooling.) Any ideas as to what the problem could be? Thank you, Mike

I have a Carrier Gas Furnace Model # 395CAV024055ABJA, I works fine if you keep the temp low, like 68, so that it doesnt come on very often, but if you try turning it up and it needs to run for awhile, it wil start this cycle where the flame will kick on and off, the blower is continously running and only blowing cold air, I have tried new batteries in the thermostat on the wall, and have tried putting it on manual heat, no change, another thing is that once it starts this cycle, if you shut it
It sounds like it is going into overheat mode. Check the overheat sensor, make sure the flue is clean, make sure any filters are clean, also check the gas passage inthe heat exchanger, if there is a blockage from soot the system will overheat ... Carrier Air Conditioners
My ruud gas heater, i had to purchase a new relay board mod.#st9101a 1014 becausemy blower would not come on when heat is called for. now I do not have any idea of how the thermostat wires onto the board. I have a 4 wire cable coming from the thermostat and a 2 wire cable coming from somewhere else. when i hook up just the 4 wire cable ,the blower relay just chatters and not enough current to start the blower please help me hook up this board
Wires R, G, W, and Y, go to the marked terminals. The other 2 wires are for your out door unit, the red will go to red, and the other which should be white will go to the yellow also. R is 24 volts hot, W is for heat, Green is for the fan, and yellow ... Ruud Air Conditioners
My 8 yr old Amana heat pump, model RHE48A2D with Honeywell progammable thermostat in heat mode has the blower running constantly. When there is a 6 to 8 degree differnce between room temp and thermostat setting compressor runs as it should, the closer it gets to thermostat setting, it will run about 30 seconds, blower continues to run until getting just cool air, about 5 minutes, compressor kicks back on for 30 sec., continues to do this, thermostat shows it has reached set temperature,
Hi, It sounds to me like what you are describing is, that when it is 6 to 8 or so degree difference then the stat says, unit operates as it is supposed to but then before it satisfies the t-stat, it shuts the compressor down long enough to start cool ... Air Conditioners
Have atwood furnace and coleman mach thermostat and it would not shut off. I unplugged power to rv and had to hit battery disconnect so that it would stop.waited few minutes...turned on...heat would not come on but blower ran until I had to unplug and start over. Is it my thermostat?Then abut 3 hours later went through the whole process again...heat came on..all well....then heat shut off...blower kept going and could hear clicking noise from furnace, (trying to light) and would not work.
It may be your thermostat, but try this first to see if time delay relay may be sticking. When it won't shut off, turn propane off, and go outside and unscrew the 2 screws that hold your cover on, and lower the cover down. Look straight ahead, attach ... Coleman Mach III Air Conditioner
Amana PTAC Unit is not producing heat. Fan works fine. can not locate manual reset for heat although a label on the unit says there is one. I have an Amana pth153b35ae ptac unit that the heat will not come on. The compressor will run in the cooling mode but not in heat mode. I verified the switching valve is working and the capacitor seems to be fine as the compressor will run in cooling mode. The thermostats seem to be functional because relays can be heard clearly when changing temperature se

We installed a Honeywell RTH230B thermostat on a Trane XE60 Air Handeler this winter. When we put the system on heat it works fine. However, when we put the system on auto for cool the compressor fan comes on but not the air handeler fan. On the air handeler the terminal strip from left to right is R W Y G B/C. The red wire on the R terminal comes from the contactor on the compressor unit. The other wire from the compressor unit is connected to a gray wire that goes to the thermostat. The W

I have a Goodman GMH950904CXAC. Thermostat calls for heat. It comes on and runs fine for about 5 minutes, then the circulator blower shuts off, but burners and draft blower still run. After another 15 seconds or so, the burners shut off and LED flashes 4 times. Thermostat is still calling for heat.
4 flashes is an overheat situation most likely caused by the blower not blowing. The blower relay controls the blower function. It is part of the circuit board. I suspect a new board will take care of the problem if you don't find a lose ... Goodman Air Conditioners
I'm not getting any heat, found a burnt wire and bad capacitor but blower won't come on neither will the coils heat up. Upon flipping the thermostat switch to fan the blower does come on. please help.
The fan relay that turns the thermostat on is probably burnt out as this probably controls the electric heat banks. ... Intertherm P3RA-042K Air Conditioner
Hi - our Siemens RDJ10RF remote thermostat controller fell off the shelf and went off as the batteries came loose. We put the batteries right and reset the thermostat remote, but the heating will not come on. Do we need to reset the boiler and how do we do it? The water still heats up, it is just the heating that doesnt respond to the thermostat anymore.

I have an intertherm rpbmb030k combo a/c and heat. Had frion put in the unit over the summer and a new digital thermostat. Unit has worked great until we needed heat. Unit works great on aux. heat but keeps switching to to defrost mode when standard heat is on. Switched out the defrost board on the unit to no avail and an a/c guy checked to ensure the new thermostat was wired correctly.
Hi, if the unit had a leak in it, was the leak located and repaired? Did he check the pressures in the unit now? If it switches to the aux mode ( Heat Strips ) is normally caused when your primary unit, compressor and freon are low on charge. I would ... Intertherm P3RA-060K Air Conditioner

First, my thermostat wouldn't shut off either my heat pump or my furnace (it runs both). Thought it was an issue with the thermostat...got a new one. Worked like a charm for 1 day. Now, there is a clicking noise coming from the heat pump - it did it at first when trying to turn it on....now, when it's warmer, it will turn on, then start to do it. Doesn't seem to be putting out hot air now. Any ideas? The thermostat came with a new box that sits inside the ceiling and it's been replaced, bu
