Here are a couple things you can do but be very careful. 1st take a voltage reading on the coil side of the contactor and see if you are getting 24vac to the contactor coil side. 2nd check your voltage on the legs of the contactor and see if they match the source voltage.

Hope this helps.

My furnace runs to operating temp on thermostat shuts down then within 30 seconds try's to cycle back on three to four times. What would cause this.


Some thermostats have a swing setting that can be adjusted. A swing is the setting when you want the furnace to stop or start from the desired set point. For example, you set your thermostat at 70 and the swing is set at 10 degrees. Then the furnace will turn on 5 degrees below 70 and shut off 5 degrees above 70. Check you thermostats manual if it has this option.

The unit is on Heat, Fan Auto it's 36 degrees outside, Thermostate set on 73 Actual temp inside 70. Unit runs continuously. How can I get more heat. I tried Emergency heat and that doesn't help.


Have you cleaned the air return filters ? Wash them, don't vacuum or brush them. It damages the filter screen. Sometimes a thermostat will be out by a few degrees. If the filters are clean, try turning the temp down a bit to 65 degrees and see if the air con shuts down. ( If your room temp is showing 70, it should switch off the machine) If it doesn't turn off, keep reducing the temp by 5 degrees at a time and wait a few minutes each movement to see if and when it shuts down. If the machine keeps running, I would suggest your thermostat is shot and you will need a new one.

Why is the AC still running after the set temp has been reached?


You may be hearing the fan run. Normally the fan will run 30-90 seconds after the unit has reached temperature to give you the air that you just paid to condition.
If it is actually the a/c running, that is because the thermostat internally reads in tenths of a degree. So when you set it to say 70 degrees, it is really set to 70.0 degrees. The thermostat will show 70 degrees when it reaches 70.5 degrees and continue to run all the way to 70.0 degrees

We have a new a/c and the system has heat strips. For a/c. we have had the thermostat set on AC at 72degrees. Now that it is getting colder and may need some heat in the house, do we switch the...


If your thermostat has an emergency heat setting this means you have a heat pump system.
Yes you need to set the thermostat to heat for heating the house.
The emergency heat setting should never be used unless your outside unit is not functioning.
The emergency heat setting overides the heat pump (the outside unit will not be energized).
The emergency heat setting will run the auxillary heat (heat strips) only.
When the thermostat is set in the heat position the heat pump will run to heat your house.
If the heat pump can't keep up (extreme cold) then then the auxillary heat will kick in to augment the heat pump until it satisfies the thermostat settings. If your room temperature gets 2 degrees below your thermostat setpoint, your auxillary heat will kick on. Example, say you are going to be gone a couple of days and you turn your heat down to 60 degrees. When you return and it is 60 degrees in your house, you turn the thermostat up to 70 degrees. Since you are turning the temperature up 2 degrees or more (10 degrees in this case) from the 60 degree room temperature then the heat pump will come on and the auxillary heat strips. The unit will continue heating like this until the temperature in the house gets to 69 degrees and the heat strips will turn off and the heat pump will continue to run until the 70 degree setpoint is reached.
Hope this helps.

I have never used central ac before - how do I set it? If it is on 75 will that cool the house? If I want it cooler, do I put it lower? like 65?


As to your question 'will 75 cool the house?' The answer is 'yes' - if the outside temperature is low enough. Typically speaking you can expect your central AC to cool a properly insulated house to a down to a temperature of about 20-25 degrees lower than the outside temperature. For example - if the outside temp is 95 degrees. You could expect to get your house down to 70-75 degrees. If the outside temp is 110 degrees then you could only expect to get the house to 85 or 90 degrees.

So .. as you can see - your 'inside' temp will be directly affected by the 'outside' temperature.

As to the operation of central air; it is very simple.

I would suggest that you not pay 'too much attention' to what you have the thermostat set on. A comfortable temperature - is a personal thing - so - I would set it somewhere - say 72 and see how I (and others in the house) was handling that setting.

If you want it 'cooler' just 'notch' it down a degree or two - if you need it a little warmer - turn it up a degree or two. Do this "fine adjusting" till you have the temperature setting you are comfortable with.

Usually the more you can leave your thermostat alone the better off you will be from a comfort position and an electrical useage standpoint. Obviously, the higher you have your thermostat set the 'less' it will cost you on your electric bill.

How high you set the temperature is a balance you have to come to based on how comfortable you want to be - matched with how much you want to hold down the electric bill.

hope this helps

Thermostat inside went up to 78 degrees which was set for 73 degrees. I checked filter filter was clogged. I cleaned filter. However could not get outside unit fan to go on even after turning off for 20...


Did the circuit breaker trip or did you turn it off and back on? If you had to remove the blower door to get
to the filter make sure the door is secured because
the door has a rocker switch that powers the entire unit.

I set the thermostat to 70 degrees but it doesnt cool down to 70, it seems that the temp in the house only rises, instead of cools down.


Setting Unit at 70* ? and not cooler ( dropping temp in the house ) Question ? does temp dop at all, if so the Unit maybe unsized, if the temps are going up then the unit is not working at all - maybe just the fan is running. If this is a split unit ( outside unit / furance). A number of things could cause the same problem - call a sevice company. it could be anything -from a Breaker to an electrical part, split Units have to different breakers ( fuse) . Check that first

When the thermostat calls for heat it should run until the room reaches the temperature setting then shut off. Is the blower motor running and can you feel air coming out of the vents? It sounds like the blower is either not running or putting out enough air to keep the furnace heating. The blower moves the heat from the heat exchanger to the room, if it can't remove enough heat from the heat exchanger there is a limit switch that will shut the burner off if it gets to hot and that's what it sounds like is happening.
