Treadmill Board Repair : Failed Power MOSFET

This video shows how to repair a treadmill board and replaced a defective components.

[@pittsville21850]

That is not capacitor leakage. It is some kind of adhesive they use to hold the caps in place.

NOTE: This product works exactly as described. kzbin.infoUgkxguEIMc_Qwab-3QMTpF6jaRL80hiOOsIN It originally earned a four-star review due to a minor defect (see below). However, the manufacturer's customer service rep (Lita) went above and beyond the call of duty and deserves five stars now. I wish I could give even more!I purchased this item which arrived quickly. Assembly instructions were easy to follow. There was only one problem: One bolt did not screw into the hole properly. I called the company. Their customer service rep (Lita) was terrific! She took all my information and submitted a request to replace the defective part. I'm hoping to finish assembly and start using this treadmill soon. (Fingers crossed...)FOLLOW UP: Lita called back to inform me that the company will send a replacement part AND a technician(!!) to install it properly. AMAZING CUSTOMER SERVICE!! Thank you!!

Great to hear!

This is very helpful to me. 👍🏻

[@jed2055]

The board in mine also has bad staining but capacitors look okay. Staining looks very old on this board. Maybe previous bad caps been replaced on my board. Did you match the bad mosfet or go with something close? Thanks for the video, it was interesting.

Nice video!

Thanks...more power..👍

It's not a capacitor stain. It's an adhesive to hold the capacitor in place.

This is my type of treadmill and I might have switch the cables in wrong places on the motherboard after cleaning. Please I need a proper connection video of this very treadmill.

Sir Thank you for your videos very good knowledge I have a sole f80 treadmill and it made a short on the negative ac to the relay pin that is on the reverse on the board where can I send you a picture?

[@biomedicalelectronicsengin7192]

That's tricky. If it's connected to relay your multimeter will read it as short because of the relay coil. Remove it from the board and test again.

Hi thanks for the video. What would cause the fuse on the pc board to blow when switched on?

[@biomedicalelectronicsengin7192]

Check shorted bridge rectifier

[@biomedicalelectronicsengin7192]

Thanks bro.

[@yut9798]

Hey man, what causes the mosfet to die out when I put weight on my treadmill?

[@biomedicalelectronicsengin7192]

What do you mean? Check flyback diode

[@treadmillrepair754]

Mosfet can fail for some reasons. 1 Bad quality of the new transistor 2 over current, motor can be failed. 3 belt, deck or both. You need a clamp meter for test the current, if the machine works for 120 volts current never exceds the 13 amps. Using a infrared thermometer you can test the temp of the belt, never be more than 45 Celsius degrees in the contact point. Best Regards.

Nice bro

[@MORJOYES]

Hi very informative. I changed the mosfet to my treadmill because was shoryted ansd as soon I started the treadmill it got shorted again do you know what is the cause in the board

[@biomedicalelectronicsengin7192]

Try to start without connecting the motor. If there is flyback diode check it if short. It is parallel to the motor connected to the MOSFET.

[@MORJOYES]

@@biomedicalelectronicsengin7192 thank you for your fast respond, I do not know anything about electronics and how to check for a shorted flyback diode. do you have a video of how to? I changed the mosfet second time and removed the Treadmill Motor Belt and run the treadmill with the new mosfet and this time did not blow up the mosfet but as soom I installed the motor belt again and run the treadmill and this time it did blow up the mosfet again. the treadmill walking belt its find. it does not fill hard to turn. its fill free.

[@antibobo4706]

@@MORJOYES a flyback diode is just an ordinary diode. In some of my video it shows how to check a diode. Similar way you check the bridge rectifier. After you replace the mosfet remove the motor connection not the belt. If connecting the motor again and blows the mosfet then you have a problem with the motor.

E6 error ba yan sir usually MOSFET Ang cra?

[@ashishshinde6374]

If this MOSFET is short then does the fuse gets blown...plzz reply...

[@biomedicalelectronicsengin7192]

Usually no. Depends on the circuit. Short bridge rectifier will blow the fuse.

[@roseelectronics4582]

I found your channel recently, and I like what you're doing. My dream is to become a biomedical equipment technician but training is not available in my country, Maldives. Can you give me some training providers name from Philippines? I prefer short term training programs over year long ones. Any help would be generously appreciated.

[@biomedicalelectronicsengin7192]

I think your country is near to India. They have a lot of programs their for biomed. But due to covid cases in India, it will be very difficult to train their. My advice is try to apply for a job in hospital or company that sell and provide service for medical equipment. They usually have their own training program. There's a lot of medical equipment and its impossible to be train for all of them. Choose your field like diagnostic, life support or monitoring. The best training is always from the manufacturer.

[@roseelectronics4582]

@@biomedicalelectronicsengin7192 Thank you for the advice. It's really helpful. I'll keep an eye on your videos.

[@kentcumberland2216]

I need your helpful advice, sir. I have ct9.3 horizon folding treadmill. It suddenly stops and a clicking sound starts coming from the motor control board. Then it takes long time to reset itself automatically and again stops and same clicking sound starts coming from the control board. What can be problem and what do you advise to fix it. Thanks.

[@biomedicalelectronicsengin7192]

The clicking sound might be coming from the relay. It will be tricky you need to test the components on the board

[@kentcumberland2216]

@@biomedicalelectronicsengin7192 Thanks for the suggestion. I will see if that will be cost effective.

Hi boss, I have also same problem in my treadmill, many times I changed my Mosfet, few minutes work after replacing the Mosfet, and again stopped working. Please help me

[@biomedicalelectronicsengin7192]

Did it damage the new MOSFET that you replaced?

I have also the same problem i changed the mosfet and machine is running but after 20 to 30 minutes again mosfet problem.3 times i have changed mosfit but it works only 20 to 30 minutes what i do?

[@waqasnettv3393]

Mosfit number is Irfp460

[@biomedicalelectronicsengin7192]

So everytime it stop working the MOSFET become defective?

[@waqasnettv3393]

Yes every time mosfet problem

Do voltage tracing. Check kung my enough power papunta sa motor. Check motor carbon brass and capacitor.

[@bumblebee8891]

Just a little info on high speed switching mosfets.Never use digital multimeter to test if mosfets are good or bad.Use analog multimeter to test switching of mosfets.🤗🤗

[@OldSkoolF]

And what is your logic on this??? I've been using them since they came out in the late 70's... Thousands of repairs and I've never heard this...

[@treadmillrepair754]

Analog multimeter in this time? What are yoy talking about?

[@champspec]

I think it has to do with the internal circuitry inside of the DMM. It will can give false readings depending on the orientation of the leads. This is just an educated guess
