What is IPM


IPM (Intelligent Power Module)- Power electronics for application embedded motor drives need to be compact and to have good thermal characteristics. Different IPM (intelligent power module) concepts are competing with different sets of features to be the best solution.Higher integration and more complex subsystems are some of the current mega trends in power electronics. Very popular are Intelligent Power Modules (IPM) for motor drive applications. They are a combination of power semiconductors like IGBTs, MOSFETs and diodes with peripheral components like driver circuits. If a whole subsystem has a good match to an application, an IPM can bring a lot of unique benefits.

My fujitsu heat pump asta12lcc not working. Operation and timer flash twice then operation flashes 3 times, cycle repeats self. What does this mean? Thankyou


Error code = Operation light x 5, Timer light x 2:
IPM protection
Abnormal current value of IPM is detected.
> Permanent stop.
[Diagnosis Point]
- Heat radiation is blocked (inlet/outlet). - check indoor and outdoor coils for blockage by dirt. If outdoor blocked, turn off power and gently hose down coils from top to bottom (that's the radiator like assembly). Don't spray upwards as you can force water onto circuit boards. Allow to dry and turn power back on to check.
- Check if outdoor fan is defective (does not rotate).
- Controller PCB defective (Refer to after mentioned "IPM diagnosis").
- Refrigeration cycle defective (Refer to after mentioned "refrigeration cycle diagnosis").

This normally ends up being a faulty controller board but there are quite a few tests that you will need to do to make sure that no other parts are causing the error. It's best to get a tech in for this one.

A short while after turning the unit on (AQV24V) it displays the error code E4 64. does mean? Thanks


  • Samsung E464 Code=IPM Over Current
Measure the current into the condenser to see if this is as per name plate,then check the gas charge

Samsung refrigerator error code 8E


8E = OVER CURRENT ERROR


IPM fault signal (this is caused by the overload of the MICOM INTO during motor action).

IPM: Integrated power module. The IPM controls the motor.

If the fault (low signal) happens to be sensed even once during the washing/rinsing stage, the motor stops immediately. However, during the dehydrating stage the signal is to be sensed, when the number of signals reads more than 6 per 500ms during the Washing or Rinsing cycle action.

If the motor stops working, in one direction ten times, "8E" Error is displayed.

During dehydrating, when the overload is sensed, the motor stops working at once and then feeds back to the initial stage of the dehydration unbalance sensing. When the feed back has occcurred twice, Error "8E" is displayed during the dehydrating unbalance sensing, No error happens by overload sensing. When it happens at more than 800rpm, the process is stopped compulsorily. Power Switch OFF can clear the overload error.

Where is the fuse box on the under dash?


There is no under dash fuse block in this vehicle, only the one under the hood. Here is the description from Dodge.


DESCRIPTION The Integrated Power Module (IPM) is a combination of the Power Distribution Center (PDC) and the Front Control Module (FCM). The IPM is located in the engine compartment, next to the battery. The PDC mates directly with the FCM to form the IPM. The PDC is a printed circuit board based module that contains fuses and relays, while the FCM contains the electronics controlling the IPM and other functions. This IPM connects directly to the battery positive through a four pin connector. The ground connection is through two other connectors. The IPM provides the primary means of voltage distribution and protection for the entire vehicle.

When I sync the outlook calendar to my iphone, one of two things happens. 1. If I put an all day event in outlook, it syncs to the iphone a day earlier (both otlook & iphone are on same date &...


Make sure time-zone is the same for both iPhone and the computer.

On iPhone setting > Mail,Contacts,Calendars setting > Time Zone Support, make sure you are choosing the city where you are in.

Otherwise, make sure you have updated the iTunes to 7.5 or later.

Update to iTunes 7.5 or later to resolve this issue. If you're not able to update, continue reading for other options to resolve the issue.
Each Outlook calendar event has an internal property known as "Message Class." When some Outlook plug-ins are installed (such as Live Search Maps), the setting for the Message Class property can change from its default of "IPM.Appointment" to something else. iPhone and iPod touch are only able sync calendar events with the Message Class set to "IPM.Appointment," therefore any calendar events created after installing certain Outlook plugins may no longer sync.
To verify this, examine the property of the Calendar event items for MS Outlook and see if the Message Class shows something other than "IPM.Appointment" in any of the calendar events. To view the Message Class property for your Outlook Calendar events, add the Message Class field as one of the columns in the Current View using these steps:
  1. Open Outlook Calendar on the computer.
  2. Choose View > Current View > Events.
  3. For Windows Vista, choose View > Current View > Customize Current View.
    For Windows XP, choose View > Arrange By > Current View > Customize Current View.
  4. Click the Fields button and choose All Appointment fields from the pop-up menu in the "Select available fields from" section.
  5. In the "Available Fields" column, select "Message Class" and click the Add button.
  6. Click OK.
  7. Click OK.
Now verify that all your calendar events are showing "IPM.Appointment" for the Message Class column. If you have calendar events showing a different value other than "IPM.Appointment" you will need to perform the following steps to fix the issue.
  1. Uninstall any Outlook plugins such as Live Search Maps or other plugins which change the default Message Class "IPM.Appointment" to some other value. Once the plugins have been removed, verify if those calendar events revert back to the Message Class of "IPM.Appointment" so that you can sync the calendar data to iPhone/iPod touch. If you are able to sync, try adding the plugins back one at a time and verify that you are still able to sync.
  2. If removing the Outlook plugins does not change the Message Class value for the calendar events, manually change the Message Class value of those calendar events to "IPM.Appointment." For more information on Message Class and how to change the Message Class fields/value, refer to Microsoft's KB article 201087 How to update existing items in an Outlook folder to use a new custom form
Good luck!

Message on screen 8E, Motor won't start on spin cycle. Model no Q1435(C/S/V)


This is what I found:
11. OVER CURRENT ERROR - Display shows 8E .
- IPM fault signal (that is caused by the overload of MICOM INT0 during motor action) is sensed.
IPM : Integrated power module. , IPM controls motor.
- If the fault signal (low signal) happens to be sensed even one time during cleansing/rinsing stage,
the motor stops immediately. However, during dehydrating stage the signal is to be sensed
when the number of signal is more than 6 for 500ms.
- During Cleansing or Rinsing
When the overload is sensed, the motor stops immediately and then proceeds to the next water-flow action.
If the stopping of the motor working is happens in one direction ten times,
"8E" Error is displayed.
- During dehydrating
When the overload is sensed, the motor stops to work at once and then feeds back to the initial
stage of the dehydration unbalance sensing.
When the feed back is continuously happened 2 times, "8E" Error is displayed
During the dehydrating unbalance sensing, No error happens by overload sensing.
When it happens at more than 800rpm, the process is stopped compulsorily.
-Power S/W Off can clear the overload error.
in short: imbalance problem
In a german forum one guy solved the problem by replacing the motor electronics. I am currently experiencing the same problem. I keep you posted.
