You are missing some numbers. It is probably a KCB_ _ _ _ _ _ .
Get back to us with all the numbers and letters of the unit and we can get you a part number for the circuit board if that is what you are looking for.

We have a Carrier A/C, Model# 2397E15183 (INSIDE) about 12 hours ago (I believe it is a fan) started making a kind of grinding noise when it starts up and when it cycles off, this is located at the bottom portion of the unit. It is cooling well and the outside unit works fine.

Infinity system. Why is the wall thermostat display blank?

Either an open control fuse at the circuit board, a fault at the circuit board, wiring to the tstat or fault at tstat.

After a thunder storm my roof mounted Carrier cooling/heating unit stopped working and now does nothing. Changed the time delay fuses and checked the circuit breakers and they seem fine. Is there a reset...

You may have a circuit board problem. Make sure you have power to the unit first. If you can, get on the roof take the access panel off to the electrical components. Most carrier circ boards have a flashing light display on the board itself. On the back of the panel you just took off should be a kiosk that tells you what the flashing means. If the light is dead, no color but you are sure there is power to the unit, the board is bad or there could be a fuse blown on the board. Most circ board fuses are a small 3 or 5 amp blade fuse mounted right on the circ board. I have seen many a carrier board burn out because of lightning. I hope this is not the case for you, as carrier boards are just a little expensive. Hope this helps you get some air back. Mark

Unable to switch on. Have checked safety switch and fuse on home circuit board - OK Power on outside unit on and OK Remote control has new batteries and display OK Cleaned remote sensor panels on both...

as per the problem which you mentioned it clearly indicates that problem is with the switch in the wall unit.but you mentioned that you checked the switch and it is OK.
this means that the problem is with the main circuit control board of the wall unit.on that board the component is got blow-ned out or any of the component is got will have to check out with meter .if it looks looks then component needs re soldering but if its faulty or blow-ned out then that component needs replacement.
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

HAD Carrier Digital unit, did not like, purchased Hunter, which I could not get to work Now I have extra colored wires hanging from the wall that came off the carrier that I did not tag.

Put the carrier unit back on the wall and connect the colored wires to the designated terminals.
R-Red, G-green(fan), Y- yellow and so on until they are all reconnected.
Manufacturers controls are designed to operate their units and sometime have more control options that require the extra wire you experienced with the off brand unit you purchased. Take it back and get the instruction manual out for the Carrier unit and learn to like it. If you have aZone System it is the only cotrol that will work with your system.
