Question about Amana Heating & Cooling

2 Answers

Unit exactly one year old. Was interruped by lightning strike last night. Afterwards air handler blowing, but not cooling? Turned unit of at temostat, waited a few minutes, turned back on and unit (both the airhandler and condensing unit) ran for about a minute, then air handler died. Compressor still running? Now the compressor will run while lowering the temp, but the air handler is dead? Tech came to our house this morning and said that both the air handler and compressor receiving power - just the air handler will not operate. They check the fuse on the circuit board, it was good. They are suspecting either blower motor or circuit board is bad? Just one year old?

Hello, if you take the L1 wire and jump it with tje high speed motor wire you can bypass the board, if this turns on the motor then you board is fried. If it does not work thenthe motor is shot and muat be Replaced. Also make sure the capacitor is not damagec.

    Thank you for the great rating, i appreciate it!

    Usually even if there are 4 wires leading out it still can be jumped with the L1 and high speed motor tap. The rest of the wires are just differant speeds and a common wire.

Marion, if there was a lightning strike and then a power surge when the power came back ON, I don't doubt what the servicemen had to say. The age of the unit plays no role in it, when something like this happens. Power surges can be killers to electrical appliances. That's why it always wise to turn the unit off during a power outage. Just ask anyone who was in Irene's path a couple of weeks ago. Power went out for days & weeks for some, when it came back ON, electrical appliances were damaged or ruined or started house fires.

Hope this helped you and thanks for choosing FixYa.

    Yes, Marion it happens that way, sometimes. Thanks for the 3-Thumbs Up Rating. I really do appreciate it.

My air handler fan does not come on, the outside unit turns on fine. Is their a way to reset the fan?


Check for fan operation by turning the fan control at the thermostat to "on". If the fan blows, it works. If not, check a circuit breaker or fuse.

If the fan blows when forcing it on with the thermostat but not in automatic, check the fan control circuit in the air handler. Danger: high voltage, beware! There should be a system wiring diagram inside the air handler somewhere.

AC BLOWS WARM AIR


Cooling comes from what is done outside, if air handler is blowing and you are hearing a sound , may be in the duct work. If you feel warm air in cooling mode then the outside unit is the prob, need more info

I have a Ruud air-conditioner/heat pump and it blows 5 amp fuse.


It sounds like the thermostat wire going to the condenser is ground, It either got pulled loose and is touching the housing or as in most cases the wire got cut or was chewed by an animal. You need to turn electric off to both devices and physically inspect the thermostat wire going from the air handler to the outside unit, also inspect where they connect inside the unit. When you find the break, cut and strip each individual wire and securely wire nut each conducter red to red white to white and so on. There you go all fixed. That's when I give you the bill for $75...except this time you write that check to yourself. Good Luck

Air Handler Blower


if you have a meat thermometer, place it in the vent when the air is on, it should be cooling somewhere around 15-18 degrees F lower than what actually temp is, so if its 84 degrees, your unit should blow around 67 degree air out of the vent. if it is not call a tech. your system could be under or over charged.

2 weeks ago one of my units stopped working properly. It got warm during the night even though I heard the unit running. I shut it off and called for repair service. They changed the thermostat and it...


sounds like the coils inside the air handler/furnace are freezing up. likely cause is the freon charge is incorrect (probably undercharged). it may have been correct when the tech did the work but some may have leaked out. it is slightly possible too that the system is overcharged. you should have the system pressure verified, and then have it checked for leaks.

Carrier Comfort 13 Puron model 24ACA3 / FV4NB006 installed 3/18/08 no longer cooling. Carrier AC1-100 Thermostat checked per manual - all default settings intact. Test override did not turn unit on though....


Verify 24 volts at the low voltage transformer inside the air handler. If it is OK, jump out the red/green and yellow thermostat wires. If everything comes on, replace the thermostat.
