SOURCE: Blower Turns off if ac unit comes on. No air coming through vents

This only could 1--2 things, a bad circuit board fan relay or bad thermostat. To check for bad thermostat, take off the front cover to reveal the 4-wire terminial and jump the red-wire (power)-cool,(yellow -y or blue)--- green--fan white-(heat)..........red to yellow-or y=cool. Thank-you-very-much!

SOURCE: My AC unit wont blow the cold air.

No, you probably have a bad evaporative fan motor, capacitor or switching. It usually takes a Pro 1/2 hour to track down such a problem with good training.

The thermostat has a timer on the on- cycle (5 min delay for the outside unit and blower inside) if you are not gonna call a service guy then ( for $25) you can go to homedepot (whatever you got out there) and buy a honeywell vertical digital heat and ac t'stat.
this one doesnt require you to set it up for a particular application. this may solve your problem. but as for warm air out of the registers you need a service guy to check that

SOURCE: Furnace stopped blowing cold.

Hi!!

Replace motor fan and capacitor, it is a very simple task. Turn breaker OFF. Then all you have to do is remove about four screws from the top grill, about four more that fasten the motor fan assembly, unplugg electrical connectors and label them and install the new one and switch fan blades.

No special knowledge is required to perform this job. Cost: about $140 +-.

On the other hand, you call a HVAC technician, they supply the motor and capacitor, otherwise they won't give you warranty. Cost $300+. Look on the Yellow Pages for one in your neighborhood.

Good Luck!! Rate this post!!

What is wrong when weather king air conditioning not coming on?


If you turn the unit to heat and say set the temp to 85 and the furnace fires up but the blower doesnt turn on after a minute or 3, 3 things to check. One is the fan control switch in the plenum. It says the plenum is hot and ok to turn on the blower. If the switch is ok, then check the blower and the capacitor. Set unit to AC and set temp to meat locker. Outside compressor and fan should come on immediately. If not
have a friend turn it on from inside while you listen outside. If you here a click, the contactor is good. If it is, check to see if the 230 Volts circuit breaker (inside in the panel) has not tripped. If thats good check the disconnect next to the outside unit. Then check for 240 AC or so on the far side of the contactor. If thats good, check the split capacitor with the power off. If all the above is good, and the fan doesnt come on, replace the motor in the outside fan. If the fan does come on and the compressor does not, see if there is a protection switch that needs to be reset. And if you dont understand the above, call a reputable dealer (ask your neighbors who they trust)

Furnace lights blows heat in cycle, pops sensor on blower and continuosly blows air until button on sensor is pushed back in


If the sensor knocks the unit off and the the fan keeps blowing without a flame ,the limit (the sensor is a limit comptroller that turns off flame @ a set temp and allows the fan to run until the heat exchanger cools to @ set temp) has out lived its lifetime and needs to be replaced.the button is a manual reset that once reset would allow the unit to continue to run flame and blower at the same time after having been set once, if it is an ongoing problem and needs to be reset more than once then replace the limit control (sensor) in kind. (With the same mode and set-points for the limits)

Furnace won't start or air condition only fan


Since you have fan operation,via fan on position, your high and low voltages are present. I would take the thernostat face off and jumper red to white for heat, if it works , the tstat is bad, same with red to yellow, if AC outside comes on.

I have air coming from the vents but no heat. The furnace is 23 years old and I've never replaced anything in the unit. Best guess? GE Intertherm. thanks


If the thermostat is set on Fan and not Auto the fan will continue to run. If the fan control is bad or is set at too low of a setting, it will blow cold air after the furnace has shut off. From what I guess of your explanation, your furnace is not producing any heat and the room air blower runs blowing cold air. You may have two issues happening. Make sure your thermostat is calling for heat by setting it to a high setting. Inspect the thermostat to see if it is set at Auto. Go to the heating system and inspect it to see if it is heating. If you can't view any flames carefully touch the exhaust pipe and see if it is hot. If not, you have a no-heat condition. A 23 year old furnace may need some TLC so call a technician you trust. He/she may need to replace the ignitor or thermocouple to get it going. They will also check out why your fan is running when it should not.

My air condition inside unit seems to be freezing up and the air stops blowing through the vents after I turn it off it sounds like ice melting. after a few hours I can turn it back on ,it will blow throuh...


When evaporator is full of ice, check the following;
Note: You may actually need the service of a qualified technician. Proper tools are needed also.
  1. Clogged filter/drier. Clean or replace filter/drier. You have to discharge the refrigerant first then recharge after replacement or cleaning. The system must be evacuated of moisture, dirt,metal chips or any particles that can cause clogging on the capillary tube.
  2. Evaporator fan. The the fan if can be turned manually. If not, realign and lubricate. It should turn freely..Otherwise it must be replaced.
  3. Refrigerant: Check the refrigerant using a gauge manifold. Repair leaks and recharge refrigerant .

My AC unit wont blow the cold air.


if the ac outside is working, but not the furnace, means there is a control problem with the furnace, check wires in the furnace, make sure there is a blower wire plugged into the contact marked cool on the control panel of the furnace

Heat Pump Stops Working only in the Early Morning


When the unit does what you say does the fan motor outside stop also , if it does that means it is in defrost mode and should kick back over to normal after the system heats up the coil enough

Central air conditoner unit doesnt blow cool air into home has some ice on the inlet heat and cooling lines going into the central air unit


Change the furnace filter. Make sure you use a cheap one when air conditioning, as the better ones restrict airflow when they filter out so much stuff and then plug up, not allowing enough air to pass over the cooling coil in the furnace's air plenum. Turn the A/C off for a few hours (with only the furnace fan on if possible) to melt the ice off the cooling unit inside the furnace.
