Ch complaint code - LG Heating & Cooling

Hi,
There are 2 possible causes for CH code.
If CH is flashing on the display then the developer unit is not installed correctly.
If CH is static then the right hand side door is not closed or closing correctly.
Hope this helps.
Dave.

What if copier show L1

Look at the book and find the code for your tv..there may be many listed...1st = hold the program button down till the red light comes on. 2nd = put your code in press enter 3rd= then try ch. up and down..tv need to be on to test. if this doesn't work try a different code repeat. 2nd way to program... turn the tv on... do step 1 then press ch. up slowly over and over till the tv changes ch. when it does...press enter..it make take 100 or more ch. ups to find your set...don't get in a hurry....

CH - open cover in the paper feed area
CH blinking - Dev unit is not properly installed
For the 'CH' check the covers and make sure all covers are closed properly.
For the 'Blinking CH' take the dev. Unit open and the reinstall unit properly.
Pls rate – thank you

CH code on a Sharp usually means the front door or a side door is not completely shut. Try opening and closing every exterior door until the code goes away. If the CH is flashing, it could mean either an optical or a heat roller fuse might have blown. Have you recently replaced any supplies?

Hello sir; CH code means somewhere the door open , it seems like right hand side door did not close right.

Actually that means your out of ink. Odd code, but that is what is means.

You would need to contact the company that makes the remote and maybe Cyberhome for the code.

I found the code...

In the remote codes guide, the Cyberhome DVD player is listed under "Portable DVD"...the code is 2083...worked for me, enjoy.

I believe a ch code on sharp is an indcation one of the covers is open.
