Usually when the furnace blower motor runs all the time
The limit switch or rollout switch is usually open or bad.
The furnace board is seeing that one of those switches is open, so it brings the blower on to try to get the heat out of the combustion chamber area, so the switch will close. But if the switch is bad and won’t close, the furnace board will keep the blower running continuously.

Testimonial: "Thank You blvl777! This does make sense and gives me a good direction to go in. I'll see if the manufacturer has a replacement part. If not then I'll apparently need to purchase another thermostat. You've been a Great Help blvl777 and Thanks Again! "

My White Rodgers 1F78 programmable thermostat shows a constant room temperature of 83-84 in the afternoon, but I set it at 77 throughout the whole day and night. Should I get a new one?


It sounds like the temp sensor is defective in the T-stat. I would replace it, get the newer programmable ones, they are very reliable and very cheap to buy online.

White-rodgers 1f80-261 thermostat: Set to heat, "flame icon" appears but no heat and no fan. Thermo doesn't click when adjusting temperature. Set to fan,there is no fan.?


There is a 3 amp fuse in the main circuit board. If this fuse is bad ,nothing will work but because of the batteries in the thermostat it will lead you to believe that the unit is working properly,however, it is only showing you what is supposed to be. Replace the fuse and everything will work.

I have a white-Rodgers 1F86-244 thermostat. When I turn the temp down it clicks on. But when left to come on its own it does not. I replaced batteries & reset it several times. Do I need a new...


Hi. This is Aaron Moratalla from White Rodgers. The clicking sound indicate the relays inside 1F86-244 are working. Say you want heat and your room temperature reading (left side of LCD) is 70F and your set Temperature (right side) is 75F. When you push the down arrow and set it from 75F to 69F or lower then you should hear the soft clicking sound. Same thing if from 69F you increase it to 71F or higher. If you don't have the clicking sound it means your thermostat could be broken. If that is the case then call our Tech Support at 800-284-2925. It's line is open M-F from 7AM to 1Am CST and Sat-Sun from 7AM to 4PM CST. Thank you for choosing White Rodgers!

Can i set it to a temperature that will allow it to turn on and off automatically


Any temperature you set it at, the AC unit will turn ON and OFF automatically. Once the set temperature has been reached and held for 5 minutes, the unit turns OFF, but the fan may continue to blow for a few minutes. When the room temperature rises above the set level, it will automatically turn ON again and continue to run, until the set temperature is reached and it turns OFF.

I really hope this has helped you and thanks for choosing FixYa.

I have a white Rodgers ac thermostat and the temperature in my apartment stays on 88 no matter how low I set the temp. If I turn it off, of course it gets even hotter. This started happening when I pressed...


I'm not quite sure I understand what you have done but, make sure your compresor(outside is running and, that you don't have the thermostat set to "fan". You want the display to show "cool" and then adjust your temp. It sounds like you have the system set to fan and not cool. Provide me with a model number and I will see about getting you a manual.

Contact the landlord or rental agency again for help. If they don't have instructions for the thermostat the Operating Manuals for many White-Rodgers thermostats can be found in PDF form HERE, however they are not indexed by model number so you will have to download each file in turn until you find the one you want. All of the file names beginning with "0037-" seem to be W-R products.*Disclaimer: I am not a lawyer, despite the handle.

I have a 1F81-51 White-Rodgers thermostat that keeps resetting itself back to the factory default settings. I've chnaged the batteries, but it continues to automatically reset itself after I have...


I had the exact same problem. Even pressing the Hold button does not really help, because once it resets - the Hold temperature also changes to the default.

I fixed this by replacing the 470 micro-Farad / 10v capacitor in the unit (it's the grey-colored capacitor). To access the back of the circuit board, you will need to break 2 plastic rivets holding the front of the unit to the base.

After replacing the capacitor I've not had any resets for the past 3 days (it used to reset itself every couple of hours).

Hope this helps.
