Carrier Infinity control went completely blank. Noticed it earlier. No matter what I push there is nothing there. Have tried manual with no luck. Any ideas how to reactivate the system? Had no noticeable problems before this. Just went blank.

Carrier infinity thermostat went blank when I touched my finger on the fan button and a static charge jumped from my finger and the screen went blank. All functions are working except the screen.


Every issue I've had with the Infinity has been a strange one. The blank screen is something I've seen and it was just a month ago. But I have no idea how I fixed it. Screen was blank but had the back light illuminated/was green but no numbers or letters displayed. I removed the tstat from its base, checked the pins on the back to see if any were bent or damaged. Tightened all wire terminals. Checked for 24v(present). Reinstalled to its base. Walked to my work truck and downloaded a manual. Walked back inside and the screen was now visable, with all numbers/letters present. I'm guessing I reset it by removing it from its power source? Also, at the indoor units' control wire terminal block, there is an A B C D. And most installers will connect 2 wires in each of these terminals. This is not correct and will give trouble due to a lost connection. You can try to tighten these low voltage terminals A B C D. The correct way to wire is at A, 1 wire is connected. That 1 wire is then connected to the 2 wires with a wirenut. B C D should be in the same way. 2 wires in this 1 terminal WILL lose connection and not communicate with the tstat. If this don't help, the tstat may need to be replaced. Hope this helps!

I have a whirlpool built in oven. Model RBD275PDQ8. The display (control panel) went blank 2 months ago. I reset the breaker, nothing. Pushed buttons, it just beeps. 3 days later I pushed the upper oven...


it's the control panel behind that touchpad item. and it's not too difficult, just time consuming. My recommend is to grab a service manual online(usually around 20.00) which will provide good step by step,and also parts list.

spares? well, that's a good question. Until you have that part number, and the best way is to eyeball the one that's in side your unit(no offense to the printers, but mistakes can happen with manuals).

then you'll find out what it's like to be truly handy, eh?

Zone control not working


These are both power open and closed. Yellow and green should be constant on the leds. C&D is your 24 volts for the controls. If you got power going in but nothing coming out of the board it is bad. If you got 24 going to the damper but damper not responding obviously it's bad. Usually communication is DC voltage, likely 12 or 13 DC at A&B. Good Luck!!

CARRIER INFINITY WEATHERMAKER WHERE IS THE RESTART SWITCH


Carrier Infinity systems, do not have a manual reset switch. It will have an automatic reset depending on the failure.
I would first, turn off the breaker to the indoor and outdoor units. Wait about 5 mins and turn the breakers back on. Doing this will reset the Control Board in the system. The system itself, is probably locked out.
This should get the system to come back on, However, you may have the problem come back and lock out the system again.
If this happens again, i would advise calling a Carrier dealer with Infinity systems to test it.

Hope this helps

Unit/control panel completely dead


Check your circuit breaker, "off" and "on" the breaker it my be tripped off. If it wont work may be some fuse blown in the control, or the control itself may be defective.
