My thermostat touch screen also failed. I replaced the wall maounted unit (not the controller mounted at the furnace) and it now works fine. If you have a high efficiency system with multiple heating/cooling settings, you will need to program the thermostat. I didn't learn this until a later furnace tune up when I was told the system was using only the low load setting. The technician programed the thermostat.

I had the same thing happen to me but the right side stopped working. I couldn't change temperatures. I wound up purchasing a new one for $100. I assumed that I had gotten some drywall dust in the thermostat when i was working in the area. I looked at the ribbon cable and everything looked fine.

I also had a display go completely unresponsive. You can do a seach online on how to reseat the ribbon cables to the unit , as that might help, or if you have two systems, you can swap displays to get the heat going for the affected zone.Ultimately I ended up ordering a new unit to solve my problem.

I had a similar issue. Remove the unit from the wall (it should just slide off). Use a cloth napkin and rubbing alcohol to wipe off the screen. Let it air dry and then put it back on. The oils from your fingers smudge up the screen (even though you can't see anything on the surface). The rubbing alcohol dissolves and cleans the screen and evaporates quickly. Very important that you remove it from the wall first as if there is any current running through it, the liquid can complete and short out a circuit.

More information is neededsuch as what system do you have. Is it just a furnace or does it incorporate central air. And what connections were on the old thermostat (w,r,y,g)?

Yes-I did the same thing but get your tech to help out. They replaced the inside unit as it is a split system. And it`s Rheem. I had a new a/c and central heater installed. 13 seer 3.5 ton

It doesn't use a regular thermostat wire use the actual wire that powers it I'm guessing u could change the thermostat

I had the same problem and was told by their customer service that a bad batch of thermostats was installed in some units. They are sending me a new thermostat, which i guess i will install myself. I also have had two issues now with the on/off switch not working properly. I am sorry I bought this unit.

If the heat pump is working and you can turn it off and on and also use the a/c, then the trouble is probably just the display on the thermostat, not the action of the thermostat. You can live without the word being displayed. A new thermostat is easy to install and cost about $100 through Amazon. On the other hand if heat is coming out when you are trying to use the a/c, the heat pump is not working correctly and you will need a qualified service technician.

My heater does the same.I had two since the first broke. I think their thermostats just dont work well.

This is also what I need to know...I have the same junk thermostat I figured this should be a nice upgrade one way or the other its going in....It's a shame you cant find decent instructions, as many people that buy thermostats you'd think that they would have a ton of instructions/upgrading info etc...

This is the second 7619 thermostat we've owned and they both have had a 5 minute delay before the fan would come on! This is for the pump to wet the pads, I know Fan Only doesn't need wet pads, but the circuitry is set up that way. Just be patient, it's working!

I have a number of them installed for separate zones. My heating system is forced hot air my supply is natural gas. I have a natural gas furnace. I do not know the differences between the pump and the furnace. Generally thermostats test for temperatures, depending on their level they will send a signal of ON or OFF. I imagine they should work in most applications.

You have to connect the outdoor sensor to S1 and S2. Then you will have to gho into the setup of the thermostat under function 0340 and turn on the remote sensor. It will ask for display or for control. Display is just to show you the outdoor temp. Control would be for different setting if you are using dual fuel application.

The thermostat retains the last settings if that is your question. If power is out, your HVAC is out of commission anyway :-)

I haven't had that problem. My thermostat follows the schedule I've programed. There may be a problem with your unit.

My furnace on my 2008 Hi Lo would not stay lit. It would cycle on an off. I read on the internet a simular problem was solved by replacing the circuit board. A dealer wanted me to bring the whole furnace in for service. I took a chance on replacing the circuit board and it solved the problem. I am not sure if you are talking about the same circuit board or furnace. I took a chance that I would be losing the cost of the circuit board.

Did you try and replace the heating element with the spare one that comes with the set? At 217 degrees, that's not even close to melting solder. I know my station has to be set about 100 degrees higher than where I normally would set it, which tells me that the thermostat isn't very accurate, but other than that I've used mine to build hundreds of circuit boards at home and actually prefer my solder station over the ones I use at work. If the 2nd heating element doesn't work, I would contact the seller.

Yea happened to me too. I emailed them and they sent me a replacement part. I was told not to max out the heat temp. So I kept it less then a 100 deg. C from the max temp after I replaced the thermol . They did not charge me for the part either. So basically if I were you and if you have time to return it for a full refund and buy another one and keep it 100 c under the max temp you should be fine. You could email them and see if they will give you the replacement part but it was a little hard changing the part. But it can be done. It's been working fine ever since.

I bought the heater for someone else so I never installed it myself. However, here is a YOUTUBE video on a 30,000 which should very similar to your. http://youtu.be/NpzbHQqWDQA I hope this help. The video says turn on right to pilot and then press the button on the left for about 6 seconds
