Put new batteries in the thermostat. Make sure that the switch that power the furnace is in the "on" position. Sometimes people mistake that switch for a light switch and turn it off.

Home a/c capacitor blew up. replaced with a smaller capacitor (only one i had on hand) now digital thermostat went blank after turning breakers back on, but works with battery. 2 year old house


The capacitor is probably not adequate or was hooked up wrong. I have three AC units and another capacitor went out this year and I found a kit with detailed instructions with pictures and phone support at hvacrepairkits.com.

Thermostat not displaying any information. when I try to jump my outside unit and blower wires everything kicks on except the outside unit.


Take the thermostat front off to where you can get to the thermostat wires. Jump R and Y together. See if the outdoor unit comes on. If it does, the thermostat is bad or may have batteries in it that need replacing. If it doesn't come on out side, you may have either a transformer burnt or maybe just a low voltage fuse blown in the furnace. If you jump R, Y and G together, the fan and air cond should work.

Thermastat reads 2 only, and air conditioner is not working


without more info it sounds like one leg on led readout went bad , i hate to say but you need to replace t-stat, in the mean time if you go to breaker panel and shut off power to both the (a/h and cond.)inside and outside unit take t-stat off the wall and disconnect all wires there should be green,red,yellow and white wires.If this is the case take yellow,red & green and twist these 3 together and put a wir nut on them.then turn power on to both units and this will get you a/c the only problem with this is, unit will run constantly until you either diconnect wires or turn power back off. hope this helps

Central air cond. was working fine 5 hours ago it went off and wont come back on. the thermastatis not lit up. it does nothing.when you try to turn air on, nothing happens at all


First ,you should verify thermostat has good batteries.secondly ,you should check to make sure the circuit breaker isn't tripped. If both of these give no results and you feel comfortable digging around the unit yourself, you will have to access the sevice panel on the outside unit to verify voltage from transformer. You should check the secondary side of transformer for 24 volt ac, as this is what feeds power to your thermostat . Hope this helps

My honeywell t8775 thermostat just went blank and now my ac just runs without colling down. Do i need a battery


This unit does not use a battery. It runs off of power from the furnace. Two possabilities. One is a problem with the low voltage power supply from the furnace. The other is that the thermostat died and needs to be replaced.
