Having problems with your Air Conditioners ?



Answers :

It sounds like a bad or tripped limit switch. The limit switch is a small disk about the size of a penny with 2 wires attached. There will be a small button between the two wires. Press firmly to reset it. Depending on your unit there could be 2 to 5 of them to reset. If they aren't tripped, then one by one, take a small jumper wire and jump them by bypassing them. You will eventually come across the "bad" one. If you can't reset it, then you will have to replace it. There is also a limit that can not be replaced that is located on the heat exchanger wall. Bypass it only temporarily to see if it is bad as well.

Hello, I have a Heater/Furnace problem. I have a Carrier 58RAV095-16 Natural Gas Furnace. My furnace keeps restarting it's heating process. Upon turning the heater on, a small fan will engage and run for about 60 seconds, then the fan turns off and the gas engages and the igniter clicks and you hear the gas combust and the flames spew out onto the heating rods(?) and after a minute or so, the big fan will turn on and begin circulating air throughout the house. Sounds all good so far? Well

Weather King 8PJ10NDR01 When I turn the heater switch to ON position the furnace runs what sounds like an internal fan. Second, the igniter glows and when it reaches it's hottest stage the fan thrusts air through the air ducts / vents and the burners light for about 30 seconds to a minute blowing cool air. After a period of about 30 seconds to a minute the burner turns off. After the igniter and burners repeat this about 2 times the heater shuts down by it's self, even when the temp gauge has no

This is a heating and cooling through the wall heat pump. It works normally when heating is selected - the heat pump runs and both speeds of the fan blow warm air. But nothing runs when cooling is selected. In other words the unit works normally when "High Heat" or "Low Heat" is selected but nothing runs when "High Cool", "Low Cool" or "Fan Only" is selected. The position of the Fan Cycle Switch has no effect - behavior of the unit is the same in both positions of the Fan Cycle Switch.

I have a LUXPRO PSP600 digital thermostat and when I switch it to heat it automatically comes on. The hot air is blowing fine. However when it meets the temperature that is set, the heater turns off but the furnace in the basement for air circulation doesn't turn off. It keeps running. (The fan with the furnace in the basement kept running.) Any help would be greatly appreciated. Thanks in advance!

I have 2 kickboard heaters in the baseboards under the cupboards in the kitchen (Smith SS7's). They are run off the hot water central heating circuit. The fan in each unit is supposed to click on to blow hot air from the heat exchanger when the temperature falls. Both units have stopped working - when one stopped the other worked intermittently for a few weeks but now this does not come on either. I have bled both units and if I keep doing this then eventually hot water reaches both but the flo

My Honeywell ducted heating at home isn't working. I have set the on/off times for the week and set it to turn on automatically but nothing happens. I think the system is connected to the gas system outside (although I'm not 100% sure) and the gas water heater works so I assume the pilot light is working OK. Perhaps the fan or the fan motor has conked out? Any advice welcome! Thanks

Friedrich YM18 230 volt heat pump. The unit has heated and cooled well for about 5 years. Just started heating mode recently and the unit no longer heats. Fan runs OK. Was able to get the heat strip to run for a few minutes (smelled the dust accumulated over the summer burning off). Now, no heating whatsoever. When in the "Money Saver" mode, nothing happens. Fan will not come on and unit will not heat. With "Money Saver" mode off, the fan runs.

Amana ptc094b35am. Whoever knows this I will consider a GENIUS or definitely connected somehow ;-) There is a series of keystrokes on the membrane control panel that will allow the fan to run continuosly when the unit is on (not only when compressor or heater is on) There is no manual switch for this. It must be programmed in the CPU via a menu accessible with a sequence of keystrokes. The only keys are "on,off,heat,cool,temp up/down" I used to have the manual but i lost it. I don't expect much

Dear friend!There is no manual switch in CPU in maximum models. But, definitely there will be fan switch as the customer should rotate for LOW,MED,HIGH . Otherwise, press mode button, if it is, you will find fan symbol. Please check once ... Amana PTC094B35AM Air Conditioner
