Question about Heating & Cooling

When the AC cuts off the blower fan runs for 90 more seconds, I have a Honeywell RTH8500D thermostat, I really don't like that, I live in Texas where the AC runs all the time.

Hello, usually tne blower runs longer to get all the cold air out of the air ducts, same thing happens in heating evcept it's warm air. You can change the blower timing by adjusting it on the integrated control board, it will say blower off timeing, this is what you use to adjust the blower timing. However, 90 sec is the least the blower will run on most furnaces.

First try replacing the batteries. I have a slightly diff honeywell model and it takes 2 "AAA" batteries. The battery holder comes out the side of the unit, just press where it says press and pull out.

I bought a Honeywell RTH8500 thermostat and I can't get the temperature to go down past 75 degrees


You will need the installation book that came with the thermostat. There is a way to enter into the programming of the thermostat from the home screen. From there, you will need to find what code is the temperature settings in the manual, they are usually all 3 digit numbers. Once you find the code for the setting your looking for which is the lowest temp for the thermostat, it will have a 75 to the right of it which you can set a lower number. Sorry I do not have the manual right now to just tell you exactly how, but hope this still helps!

HONEYWELL RTHL2310/RTHL221 THERMOSTAT AIR WILL NOT COMEON


Recheck your connections.The wire colors may not have been wired in the standard way when HVAC system was installed. I remember the instructions on my Honeywell thermostat(replaced mine about 2 months ago) stated that you should look at the wire LOCATIONS on the 'stat you're replacing and tag the wires according to this,not the wire color(too late in your case).You'll have to verify the wires.Disconnect them(don't worry about noting where they were as it's not right anyway).Using an A/C voltmeter,locate the hot feed to the 'stat(ground one lead of the meter at a nearby outlet and look for 24v on any of the wires).Tag it as "feed".Now,touch this to each wire until you find one that turns on the ventilation blower and tag it.Try the other two,one of them should turn on the outside A/C condensor unit(this is the A/C wire).The remaining wire's gotta be the furnace,but verify anyway.This should be enough to get you back on track(don't feel bad,the instructions in my 'stat confused me a little,even though I've replaced mine a couple times before).PS- I think the blower fan wire goes to the terminal with the little factory jumper wire-this is so you can set it up to run the same fan in heat or A/C(factory setup) or remove the jumper to run a seperate fan for each(highly unusual setup but possible)

Theres a snowflake type symbol flashing on my honeywell thermostat and the air is not working


When the snowflake is blinking it usually indicates something is wrong with your AC. The first thing you should do is to verify that the power is there and don't forget the switch to the blower next to the furnance.

Then see if the exterior fan is working/spinning. If it isn't, then it could be the contactor-relay or the capacitor or the compressor. I always recommend that the contactor-relay and capacitor be replaced at the same time because they have similar failure rates and if you replace one now, the other might fail shortly later, but use your best judgement. They aren't that hard to replace, but make sure the power is off before you do it.

You can find the contactor-relay and capacitor from this site: http://www.hvacpartsoutlet.com/Goodman-45/5-mfd-370-Volt-Round-Dual-Run-Capacitor-CPDRG455.aspx and if you aren't sure which one to order ask the site and they will help you.

Now if the compressor is bad, which you can check with an ohm meter, then you will need a professional to change it since there is freon to be captured and then to charge the system.

Have a honeywell thermostat t6575b1003 and my a/c unit wont get below 90, is this a thermostat issue?


Does it feel like 90 where the thermostat is located? If it's not hot in that location, then your thermostat is most likely going bad as far as the temp. goes. If the A/C isn't cutting off, then the thermostat doesn't know what the temp is to cut off. I would suggest replacing it if you have these symptoms. If it feels 90, you need to have the unit A/C unit checked out.

I turned on the ac and the light does not work, the vents are not blowing and the car is running hot. I have a saturn SL 1996


First check the 15 amp HVAC fuse located in the main fuse block inside the car on the passenger side of the center console, under a cover. If the fuse is good, then the problem may either be the HVAC blower switch (which is the fan blower selector switch), the fan blower motor resistor, or the fan blower motor. An auto repair manual will explain and illustrate for you the steps on how to check each of these components.

Even after pushing the ac light switch on, the fan blower selector switch has to be turned on as well (working) because it provides an electrical path to the positive side of the battery to complete the circuit and turn the ac light on. What the ac light switch does is provide the electrical path for the ac compressor clutch to come on through the ac control relay which is controlled by the car's PCM(computer) when you want ac, but the ac light switch still needs to run through the fan blower selector switch to receive its power. You can turn on the fan without the ac light switch because it gets its ground path(negative) from the blower motor. So the blower motor has to work in order to provide a ground path for the fan blower selector switch to be functional. You could have a faulty blower motor which is why no air blows through the vents. The fan blower motor is located inside the car on the passenger side underneath the dash at the bottom end of the glove compartment box. You'll see it. It's right above where a person rests their feet on the floor. Therefore, if your 15 amp HVAC fuse is good, check to see if you have voltage at the blower motor connector. Unclip the connector and with the ignition on and the fan blower switch moved to any one of the first 3 selections, check for voltage using a multimeter. The voltage will vary because there is a blower motor resistor. Voltage should be higher on setting 3 than 1. If you do have voltage at the blower motor connector, check for a faulty blower motor. The auto repair manual will tell you how to do it using jumper wires.

It's normal that your car is running hot because the radiator fan works in conjunction with your ac compressor. If the ac is on, the radiator fan will be on and therefore the engine coolant temperature will stay in it's normal operating range. If the ac is off, the radiator fan will stay off as well and the engine coolant temperature gauge will begin to rise and show pretty hot (especially at idle). It will do this up until a certain degree then the radiator fan should turn on thermostatically and stabilize the temperature. It's scary and I know what your saying because it does that to my car if my ac isn't on. Don't worry it won't overheat.

Honeywell thermostat RTH6300b will not shut off at


I had this same problem with my 6300B thermostat. I did not see this when I installed the tstat and did setup for it the first time. If you go to page 16 of the install guide, there are instructions for setting up your tstat for your furnace and AC. The setting I had wrong was on page 20 of the guide. It defaults to a setting for a furnace/ac that is less than 90% efficient. When I changed the setting to a furnace that is more than 90% efficient, the fan not turning on or off problem went away. The setting on page 20 should be set to "3" if you have a more than 90% efficient furnace/ac. Hope this helps your problem
