L series fault code question
We have an L series and it is generating a code 88 which is a problem with the ecto chip. The result of this code is that all ecto settings will revert back to the factory settings which is exactly what has happened and it is very very bad for us.
Has anyone ever had this code and found out exactly what is causing it.
The unit is functioning normally but has started to generate this code and some other codes....but unfortunately the two guys who have been there have not been writing them down..
they both did remember the 88 code and they have also reported codes related to communication... I guess between unit components because there are no controls on this unit....no L network...nothing... and there have also been enthalpy related codes but Im thinking that this might be due to their being an add on accessory economizer board mounted to the main board....but the economizer harness has been disconnected due to the job this unit is doing....
Main board probably sees the add on board and is expecting some information from it...
Im going down in the am.... gonna have to do some jerry rigging to get around the ecto reverting back to factory settings.... but Im just wondering if we need to get a board on order or if something in the etco settings could be conflicting with something else and causing this error.
any help would be appreciated,
thanksLet go of my cracker jacks, If you dont Im going to have to beat you....... now then hand my captain crunch back over to me this instant.....or else !!!

Error code (88) indicates there may be a problem with the ECTO chip. The action the IMC will take is that the unit will operate on factory default ECTO settings. Check all your plugs and connections, but you probably have a bad ECTO chip.
Isn't there a detailed list lamented to the inside of the cabinet door? Whoever installed the unit should have left the book inside the little rack inside the door.

Thanks for the response biodieselman..... I understand what code 88 is and I also understand that all etco parameters have reverted back to their factory settings.
Im just trying to find out if anyone else has gotten the fault before and if they fiqured out the root cause of it.
Ive never seen the code come up before and we have a lot of these units out there. I dont know if some parameter conflicting with another....or an electrical bug somewhere or what...or if the chip has just "gone bad"....
Dont want to waste time looking for something that isnt there....but then I dont want to replace a part and have the problem come up again a week down the road...
thanks again...Let go of my cracker jacks, If you dont Im going to have to beat you....... now then hand my captain crunch back over to me this instant.....or else !!!

Anyhow....... I went down there yesterday and found the unit display flashing numbers in rapid sequence..... and the temp dip switch in the on position.
Evidently the people there didnt know how to retrieve the codes properly and someone at some point had been viewing temps....and not put the temp dip switch back into the off position.
I dont know why it was flashing all those numbers. Usually you need to scroll thru the temps with the pushbutton.....maybe after the dip switch being on a while the board just start flashing random numbers. Or someone might shut off the disconnect and then turned it back on with the switch in that position causing the flashing numbers....
I did this yesterday (worked the disconnect off then back on while the temp switch was in the on position and it did the same thing)......so Id say its just something with the way it works.
Board is working fine......unit is working fine....
false alarms.......lolLet go of my cracker jacks, If you dont Im going to have to beat you....... now then hand my captain crunch back over to me this instant.....or else !!!
