I am not able to get the unit to change from air conditioning to heat


Unfortunately these units are not user fixable , beyond checking for power and checking battery in remote. You would need to call a pro who is able to get service information and has special digital logic meters to diagnose and repair .

U8 detail 61


Hi,

U8 is the ADF Set-up Error. This error is displayed when Pick roller unit is locked in the upper position, release(lower) the Pick roller unit to resolve the error. Secondly, if the hopper is over loaded, reduce the document load on the hopper.

Hope the above information is helpful.

Thanks,
Scancare

Hi, I can't find that specific error code in the documentation on that model of machine, however, in general in Xerox machines U8-3 means that your exposure lamp is blown or has a problem

RHFE-1004FA 38,400 BTU Energy Saver Ductless Heater - LP Gas: water heater gives a code 12...


Error code 12 on a Rinnai means the unit lit, sensed a flame but then failed to sense it some time later whilst in operation. Most commen faults causing this are gas regulator based on LPG systems. The regualtor fails to let enough gas through to continue powering the burner. I did have another where the guy had put a natural gas model on LPG supplies, you didn't say if this fault was on a newly installed sysyem or not!
One other cause (not so well known) is if you when you get a 12 immeadiatly you turn the tap on. This is caused by a short circuit on the low voltage side of the heater. I'm guessing you have controllers to display the error code. I've had a few where a bit of DIY work has put a nail though a wire supplying the controller and caused a short. The wiring is only 12 volt so it doesnt blow any fuses. If you do have controllers, get a qualified person to remove the front of the heater and disconnect the controller lead from the circuit board, see if this stops the fault. If it does, try and find the short in the wire (even had rats cause this in one location)
If this doesnt work get the technician to check the overheat loom around the heat exchanger, this is another favorite place for the wiriing to short.

Happy hunting.

No heating from Mr slim


P8 refers to outdoor protection device activation usually caused by low gas charge or blocked condenser coil. any good a/c company can resolve this for you. however please note that if it is gas related a pressure test must be carried out to determine where that potential leak may be and that can be very costly.

Problem with mitsubishi slim


I am not familiar with a P8 code nor do I understand where you are seeing this But, go to mrslim.com and look under Customer resources, Library and then input your model number. Select Technical & Services. Product Catagory is Mr. Slim Ductless, Sub Catagory is M-series Multi Split, Current models. Remember you have inside units and one outside unit. You will need to look at each model number to find information on both. Usually Mitsubishi's will have two lights that will blink in patterns to indicate what could be wrong. The P8 code is new for this Diamond Dealer!
