\015 I have bard central unit model# a/c ph11361 serial#1750991338Z77-1 my problem is every thing works except blower motor the voltage going to motor is 115vlts shoulnd be 220vlts? my questions were is my voltage drop? and how can i ck to find problems cking across wires no voltage but each leg to ground 115vlts thanks\015

Answers :

If your unit is a gas unit, then its 115v and if its and electric unit 220v. If you are getting voltage to the motor, 115 to ground but the motor isn't starting then the motor is bad. The black wire is high speed, red is med., blue and or yellow is low. The wite wire is neutral. Black wire is used in heat mode and blue is used for cool. If you are checking voltages you will only use one of the colored wires with the white wire and you will only have voltage for the one that the tstat is calling for to come on. Hope this helps.
220 is just putting two 110 volt circuits together. You should read only 110 volts from each leg to ground. But you should read 220 between both legs. Measuring between two legs that are supposed to be 220 and you read nothing than you are not measuring the differences. This means you are only getting 110 volts. Check your units data plate and make sure you need 220. Usually the condenser fan on a split system is 110 volts and the condenser fan is 220 volts. Which motor are you checking?

I have an old RUUD central AC unit that started blowing hot air. I set the thermostat to off and set the temp gage higher than air temp to turn the unit off and save money, but inside blower unit runs constantly. I'm trying to save money to have it serviced, but noticed my electric bill was higher that last month when the ac was working. The bill was about 4 times higher than the winter when ac is off and the gas heat kicks in. Can the blower running constantly cause this power usage and what is

I have a Coleman roof mounted AC unit on a travel trailer. The unit model is 83338715. The unit just blows cool air not cold air like it should. I was told to replace the "Hard Start Capacitor" and "PTCR Start Device" which I did. This did not remedy the problem. Any thoughts would be appreciated. Could the problem be the "Compressor Run Capacitor"? Reason being that I hear no change in the blower sound when the unit kicks on???


Blowing 'cool air' could mean - room temperature air or it could be 'cool' because the system is low on refrigerant, and just barely doing any 'cooling' at all.\012\012To determine which is which - you need to know "for sure" if the compressor ... Air Conditioners

My compressor unit outside runs and cools Freon but the inside blower has a problem running. the model # is 2TEE3F31A1000AA. The fan control, in fan run control mode, shows a bright green for the fan LED and the CFM selection LED varies with the rotational speed of the fan. The motor tries to start showing , initially, a jerky back & forth movement. It squeaks some and may, or may not, start rotating. If it starts the CFM LED goes bright/on no flicker and the motor runs briefly (5 seconds) then

The model number as listed on the receipt is CKQ24. The Blower moter in the air-handler is not running. When the fan-only switch is turned on, the blower motor will attempt to spin by pulsing for about 2 seconds. It will repeat the pulsing cycle in about 2 second intervals. There is no smell of burning. When the unit is set to AC and auto, the evaparator coils do chill. The blower motor is a variable speed motor with an external ECM. How do I test the ECM and/or motor? What should I look for in

I have a Arcoaire Gas Furnace (Model# GNJ100N12A1), that will not fire up. It has a White Rogers Digital Stat. First the Stat seems to be faulty, since it reads 70plus in a house that has a temp of 30 or below. I can adjust the Stat and the blower motor will run. The rollouts (3) were reset; the inducer fan would run; then the unit would cycle and shut off. Now the inducer won't run. The ignitor is good, but would never glow. A friend tested the current coming from the Stat, and found 24

I have a rheem electric furnace with 2 speed fan, seems like the fan runs full bore when its on, even when i just cycle the blower control to ''on'' and its supposed to run at reduced speed.

If it is a variable speed blower most likely the dip switch settings. Check the installation manual to see how to slow it down. ... Air Conditioners

With unit set to air conditioning, the controller board will not turn on the blower motor and the cooling coil freezes up. McNutt tells me the controller board is kaput and they want $550 for it.
