SOURCE: unit stops working - E1

I wrote the solution #1 and have an additional comment. This really does work!! I fixed my neighbor's AC unit by following the instructions for clearing the E1 code. The unit will not operate until the code is cleared. The page is titled: Customer assistance for air filters cleaning (E1 code) on Sharp Air Conditioners

I would first check the condensate drain pipe. This can be done by blowing back into the drainpipe from outside. Not to worry it is not dirty or dangerous. Also make sure that your air filters are clean.

It sounds like your inverter is at fault. You will need an inverter tester ( most good service techs will have one ) to prove that the output to the compressor is correct. If the inverter is okay then it will be the compressor at fault with a location error or it is simply seized. A common fault that caused this was the eev remained closed (coil failure ) and caused the compressor to over heat.

My Panasonic split air conditioner has stopped cooling - model:CU-W18DKR. The internal unit and internal fan operate normally. The external unit fan does not run like normal and no compressor sounds f


Sounds like a faulty outdoor controller board. If you are in Australia, call Prime Electronics or Statewide Appliances for spares.
Part number: NPCWA743383

• To make a diagnosis
1. Timer LED start to blink and the unit automatically stops the operation.
2. Press the CHECK button on the remote controller continuously for 5 seconds.
3. "- -" will be displayed on the remote controller display.
Note: Display only for "- -". (No transmitting signal, no
receiving sound and no Power LED blinking.)
4. Press the "TIMER" or button on the remote controller. The code "H00" (no abnormality) will be displayed and signal will be transmitted to the main unit.
5. Every press of the button (up or down) will increase abnormality numbers and transmit abnormality code signal to the main unit.
6. When the latest abnormality code on the main unit and code transmitted from the remote controller are matched, power LED will light up for 30 seconds and a beep sound (continuously for 4 seconds) will be heard. If no codes are matched, power LED will light up for 0.5 seconds and no sound will be heard.
7. The breakdown diagnosis mode will be canceled by pressing the CHECK button continuously for 5 seconds or without any operation the remote control for 30 seconds.
8. The LED will be off if the unit is turned off or the RESET button on the main unit is pressed.

Or better yet, get a tech to check first.

How do I fix the H98 error on my microwave


You haven't identified the brand, make or model but this may be helpful:

Newer Panasonic Microwaves have built in fault codes....

they look like H97, H98....
Troubleshooting of Inverter Circuit (U) and Magnetron
This oven is programmed with a self diagnostics failure code system which will help for troubleshooting, H97, H98 and H99 are the provided failure magnetron and inverter circuit problem areas. This section explains failure codes of H97, H98 and H99. H97, H98 and H99 appears in display window a short time after start key is pressed and there is no microwave oscillation.

NOTE:
DO NOT try to REPAIR this Inverter Power Supply (U) and also DO NOT RE-ADJUST PRESET VOLUME on the board. It is very dangerous to repair or adjust without sufficient test equipment because this circuit handles very high voltage and very large current. Off alignment or inverter board operation is dangerous. Operating a misaligned inverter circuit is dangerous due to the very high voltage and current that is produced by this board. Defective boards must be replaced with a new one.
- Check magnetron filament for open or short to casing before proceeding to determine a good magnetron.
Alternative way to troubleshoot oven with AC Ampere meter used.

Not sure if yours has a letter 'H' before the 16 but if it does, it's the:
- Outdoor Current Transformer open circuit.
which means that your outdoor controller board is faulty.

I have a panasonic reverse cycle ducted air conditioner Panasonic model cu 71c 5 2hp. The word "check" is flashing on the display - when I press the check button, error code " F00"...


F00 fault is a short circuit or grounding out in the low voltage (safety) circuitry. Check in your thermostat (Y1). Hope it's helpful?

Hi, I have a Panasonic Inverter microwave NN-Sn9688. It's less than a year old and when you press the START button H98 appears and it will not start. Everything else works, clock etc and reset/stop...


Hi Judith, I am Kelly

If this has a 1 year warranty it is time to make that call.

Otherwise see this link about H97 or H98 codes: http://www.applianceaid.com/micro_faultcodes.html#panasonic

There are a few things that can cause the problem, none of them cheap repairs. The Magnetron filament, Control board and Inverter are the top 3 other than a losse connection.

I tried running the Model number NN-SN9688 and it does not cross. See Panasonic link here: http://www2.panasonic.com/webapp/wcs/stores/servlet/PNAEndecaSearchCmd?N=779832097&Ne=&No=0&Nr=12001&Ns=&Ntk=SupportSearch&URL=vSupportSearch&cmTag=true&catalogId=11017&storeId=15001&cm_sp=SiteSearch-_-SupportSearch-_-SupportHome&Ntt=NN-SN9688&x=28&y=20

I did not go to Panasonic Global and try other countries. I just did a USA search.

Thanks for choosing FixYa.
