Panasonic Inverter aircon E24DKR icing up inside unit
My panasonic inverter aircon ices up on the inside unit.. when I look inside the unit there is lots of ice on the metal fins. If I turn off the unit for an hour or so it 'thaws' ou and works again but only for a while.
So on hot days, even with the cooling set for only 24C it still ices and blows out only a very small amount of cool air regardless of setting (quiet/powerful/normal/fan speed).
I have cleaned the air filters: they are ok (and clean them every 2w or so).
Looking at the pipes to the outside unit, they seem ok and there is some water dripping from the outlet one an no ice on the outside pipes.
Is this something simple as needing some more refrigerant? I think we have had the aircon 2-3 years.

Unplug the power cord or if you are unable to turn off power that way, use fuse box and leave power off for 20 minutes. This should enable the system to reset to default settings and you can then set system to your needs.
If it is displaying error H97, or h98, this generally means that the invertor(power supply Panasonic part
number: Z606YM300BP,) is not functioning. The magnetron may also be faulty.
Here is some more information about the part. The microwave may also
have a faulty magnetron. If you are unsure, then you should get someone
to look at the unit for you before you go buying parts.
BEWARE... VOLTAGES INSIDE MICROWAVES CAN KILL
number: Z606YM300BP, supersedes all previous versions of the inverter
used with the 2M261-M32J This Inverter is now available at a lower
cost, it used to be £60.00 plus VAT and delivery trade price.
This inverter is fitted to many of the more
recent Panasonic inverter type microwaves such as the NNC596S .Some
microwaves such as Bosch and Siemens also use this inverter as they are
rebranded Panasonic ovens. These ovens are upmarket models, some
include advanced functions such as steaming and are normally well worth
The inverter as fitted to earlier ovens with the
2M236-M42 and 2M236-M1 is also available.
An inverter microwave oven is one without a high
voltage transformer You will know you have one as it is not extremely
heavy at one end. This type of microwave uses a high power DC
converter, called an inverter, to produce the high voltage and filament
voltage required by the magnetron.
If you purchase this item for replacement in your
microwave then we recommend that you do this only if you are qualified
and aware of the dangers of tampering with electrical equipment.
Failure of the magnetron is common and at times
the inverter can fail as well. Sometimes the inverter fails on it's
own. If your microwave blows the 10 amp mains input fuse as the cooking
cycle starts then you probably need a new inverter. An instruction
sheet with basic guidelines on fitting will be provided but please do
not purchase this item unless you are confident about fitting it. We
only accept returns if the inverter supplied is defective which is
If you have one of these ovens that is not cooking then it is
worthwhile looking at the magnetron. It often shows signs of distress
As well as the inverter failing it is also possible you could also have a defective magnetron,
Good luck and thanks for using FixYa
A FixYa rating would be spot on for this information to you.
I found this error. The simple possible resolution is to reset the circuit breakers feeding this unit and/or replace possible blown fuses. Other possible problems may be too involved therefore a professional should be hired. Just a warning, this problem could get expensive.
the digital programmer circuit / controller does not get a feedback
signal from the inverter for a period of 3 seconds, the controller will
stop the cook cycle.
it stops after 7 seconds, it has a problem with the inverter.
It may be a loose connection in the wiring between the
inverter, magnetron, and/or control board, or maybe one of
components has failed.
Due to the lethal
voltages used and produced in inverters, I do not recommend that an
inexperienced person work on these.
Hi, If you are in the cooling posistion, you need to check the filter on this unit as when they get plugged up it will cause the evaporator coil to ice up and condensation to overflow down the front of the indoor unit. This is where the filter should be located behind the front cover. You may have to brush dirt from the coil carefully, and try and flush the drain for the condensation to run out the line or hose. This should take care of the ice problem. If you are in the heat season, let me know and we will go from there. Just look me up. Sincerely, Shastalaker7 PS The filter may be foam. If so, just wash it out and ring it out. This will clean it.
The drain outlet is blocked on the outside of the unit. Blow into it to clear blockage. Also check that the air filter on the inside of the unit is clean. If dirty it prevents good airflow over the coil causing it to ice up and overflow past the drainpan.
HI, if this unit is totally dead, this may be a power inverter issue. there is a fuse located on this board inside the unit. you will need to gain access to this board and fuse by removing the outer cover. there should be a few screws on the outside of the microwave to remove.
Check the In-line fuse for its value. if the fuse is good, replace the power unit(inverter board)
the main control board is "seeingf" a high amprage draw from the inverter board . you have a problem with the inverter or the magntron . parts are more than a new unit . try to stay away from the inverter type , there just not ready for prime time . google "panasonic inverter reviews " and you will see just common your problem is good luck
