DIY Series 51: Repair Bread Maker (Trio TBM-111)

When you see your bread maker's kneading blade is not rotating when you press Stop/Start button, you might think that it is time to get a replacement unit.

In fact, the bread maker is still usable, just need to do a minor repair. I had another similar DIY on Morgan Bread Maker MBM-1020 previously.

This time, I am working on fixing of Trio TBM-111.


1. Open the top lid and take out the bread pan


2. Turn the bread maker upside down and unscrew 6 screws


3. Use a screwdriver, unlatch the top cover from the base



4. Open the top cover slowly and detach the control board connector in order to be able to remove the top cover completely


5. Unscrew 4 screws to remove the inner housing



6. Unscrew 7 screws at the base metal plate in order to see the belt


7. Flip over the base metal plate and you will see the old rubber belt is no longer exist. Only remain the debris and also a bunch of strings stuck at the motor rod


8. Clean the motor rod and the gear (at the bottom of kneading rod), remove the strings. Then, replace with new rubber belt.


9. Reassemble the unit back to its original condition.


10. Power ON and test the Bread Maker. If  none of the buttons (except Stop/Start button) is functioning when it was pressed, try to press and hold the Stop/Start button for 5 seconds to reset the program to default setting.

It was told that the Panasonic Air Purifier (F-VXT90) was malfunction, unable to power on. The owner wanted to scrap it, but I managed to fix it with just merely US$0.50.



Photos (PCB Debug & Repair):
  1. Power Module PCB was taken out to check the malfunction parts
  2. Burnt parts identified (T3.15A Radial Fuse & Varistor 07D221K)
  3. Desoldered the broken parts
  4. Broken parts (Zoom In): Visual inspection and open/short test using multimeter
  5. Replace new parts (T3.15A Radial Fuse & Varistor 10D221K)





Photos (Suitable Parts Study & Sourcing):
  1. Function of Varistor (Circuit Protection)
  2. Comparison of Varistor 07D221K vs 10D221K (to check on compatibility for replacement)
  3. Sourcing for radial fuse (T3.15A, 250V)
  4. Sourcing for varistor (use 10D221K to replace 07D221K, due to part unavailable from local market)

XMUM is located at Bandar Sunsuria, very near to KLIA. It is just one station before KLIA Terminal 1 if you are travel by ERL (Express Rail Link) or more commonly known as KLIA Transit. The nearest ERL Station is Salak Tinggi Station.

It is merely 20min walking distance from XMUM campus to Salak Tinggi Station via Sunsuria City Le Park jogging track (with 24hrs CCTV monitoring).

  • Le Park Jogging Track (Satellite View)

From Salak Tinggi Station, there are many options. You can choose to travel via:

  1. KLIA Transit: Taking ERL all the way to KL Sentral (RM18.30) or KLIA Terminal 1 (RM4.90)
    For higher learning institutes students, refer [ KLIA Transit MyKad Concession Fares | KLIA Ekspres ]
  2. MRT/LRT: Taking ERL to Putrajaya Sentral (RM4.70), then transit to MRT Putrajaya, and you may opt to take LRT at certain connecting stations within KL
    For Integrated Transit Map, refer [ KL MRT, LRT, Monorail ]
    For 1-Day Pass, refer [ MyCity Pass - MyRapid ]
    For Student Card, refer [ Concession Cards - MyRapid ]
  3. Buses via KLIA Bus Terminal
    For KLIA bus terminal, refer [ KLIA Bus Terminal: theairportbus.com.my ]

It is very convenient to take a bus to other destination via KLIA Terminal 1.
