Fan runs constantly on cool mode

The cooling fan never shuts off in the cool mode. Worked perfect last summer. Works perfect in the heat mode. The heat pump shuts off and cycles as normal but the room temp isn't maintained in the cool mode. just gets colder. I'm thinking the relay must be stuck or maybe a bad temp sensor.

Simple Question: Did you check to see if the fan switch on the
t-stat is in ON or AUTO? If ON the fan runs nonstop. If in auto the fan cycles with the outdoor unit.
next does the fan shut off if you turn the t-stat to off?
A stuck relay should keep the fan running all the time.
Sometimes if the relay is stuck you can whack the side of the Air Handler and the connection will break.
Sometimes instead of a relay there is a stack switch.
It's a little black stack of 3 disks this is a bi-metal switch.
they do get stuck more often than relays.
The fan relay may be on a electronic board. I don't know for sure without seeing your unit.
Good Luck Phil

Heat Pump - blows heat to set temp, then off, then kicks on to blow cold


Heat pumps defrost which is the AC mode, if the heat strip isnt working during a defrost, the air will be cold, A heat pump only feels warm if the heat strips are on too! the refrigeration cycles heat output is much less sensible to our 98F skin. heat pumps that satisfy a room setpoint are working at least, all heat pumps feel drafty to most.

If you changed the unit but didn't change the thermostat it is possible that the thermostat that you have will not work with that unit. I see that the unit you installed is a heat pump, you may have a straight cool T-Stat. If you put the T-Stat in the "Auto" "Heat" mode the outdoor fan and the compressor should be workng as well as the blower fan. If it turns out that the outdoor fan and compressor are not running you will want to buy a Thernostat that is compatable with heatpumps should be 2 heat/ 1 cool

My Lennox Air conditioner only heats


It is possible that it's the thermostat. When you turn it into cool mode, does the unit come on at all or is it silent? If nothing is coming on, then it's likely it's the tstat. Did the tech check the refrigerant charge while he was there? He should have checked it with the auxillary heat off and the unit just in heat mode. Make sure that the condenser unit outside is coming on when you are calling for cool, If you turn it on and everything comes on, go outside and put your hand on the large copper pipe coming into the unit. In cool mode, this pipe will be cold to the touch and in heat mode, the pipe will be warm to the touch. There isn't much you can do on your own with the exception of changing the tstat. If you can answer some of the questions I have posed, I can try and give you some more answers. Just remember that a check up doesn't mean its a guarantee that something won't happen the next day, it's just that everything was in working order at the time of the checkup.

Just a little question, guys!


The blower has absolutely nothing to do with outdoor air. Having the T-Stat set to auto lets the blower come on only when the A/C-heat comes on. With the switch in the ON position the blower simply runs all of the time. Depending on your living space (high ceilings, multi-level) having the blower on constantly while costing a small amount to run can actually save some money and make you more comfortable in the summer. However most people will leave it in auto in the winter so they don't feel as if they have a draft from the air movement as the blower is in high speed in fan on position and cool modes and low speed in heat mode. Many furnaces today are equipped with a setting that allows the blower to run constantly at a lower speed or simply run for a min. or two after the A/C=Heat have turned off.
