My friend has a Samsung refrigerator

Found a very good video

My friend has a John Deere 100 riding mower and it won’t start, after doing some research and checking out my own note, I think there are two possible places that might cause this.

I found these helpful videos and they provide some visual information for this

1. The starter solenoid coil failure
2. This lady did a good job on cleaning carburetor, successful story.
3. There are some common mistakes in starting the engine wrongly. 

I am writing this note to program a Kwikset Powerbolt Deadbolt Lock, and I find this helpful video. The guy did a fantastic job and he really deserves the credit. If people prefer to read instruction manual, here it is: powerbolt2-programming-instructions

A few important reminders:

The powerbolt is powered by 4 AA batteries
The reset button is located at the back (inside) of the lock, by pushing it down for 5 seconds until it beats, 
The manufacture master code is always: 0-0-0-0. 
Never make the master code same as the manufacture's master code
Beeping for twice is a successful sign, while beeping for 3 times is a bad one.

To reset the lock and get ready to program the pass code

1. Make sure the lock is in the unlocked position.
2. Remove the battery cover.
3. Press and hold the “Reset” button for 5 seconds. You will hear 3 long beeps after the 5 seconds is completed indicating the lock has been reset.

As a result, You will reset your User Code to 1-2-3-4 and Mastercode to 0-0-0-0 when the reset is complete.

To set locking/unlocking positions

1. Make sure the door is open and in the unlocked position.
2. Press 0 – 0 – 0 – 0 – LockSign – 0 – LockSign
Note: Each button represents two numbers (i.e. ONLY push the button once for 0). If you incorrectly enter the code, wait 10 seconds until you hear three beeps. Then you can try again.
3. If the step was completed correctly, the latch bolt will extend out and retract back in completely.
4. It should beeps twice.

What can go wrong, if you hear it beeps three times.

	
It must be set at completely unlock position
	
If you missed, it can be fixed by
	
Use key to turn it to lock position, then do:Press 0 – 0 – 0 – 0 – LockSign – 0 – LockSign
	
It should retrack back to unlock position, then reset to manufacture setting
	
Then re-do it.

To test the lock

1. Make sure the door is open and in the unlocked position.
2. Press LockSign
3. The latch will extend fully to the lock position and end with one beep and the keypad will turn off.

NEVER make user’s code as “manufacture default master code”, it allows up to 6 different codes.

This is a pretty cool video explains how an expansion tank function.

I shared this video with yicheng how to install an expansion tank.

We consider replacing the anode rod and this video provides very good tutorial. It seems simple, but to screw it back can be very difficult. Sear also provides detail instruction as well.

It turns out that we need to replace the heating element from this (videos) but the themorstat seems fail so we want to test the thermostat.

To replace the heating element, we follow this video. Again, nothing works easily as the video shows. In our case, we have hard time to screw the element back.

Here is the CV boot diagram for Sienna part number: 4342008091.

I am helping son to fix his house gradually,

Task 1. Fix the hole in the hollow core door

This guy gives a very good demo on how to do it, very detail and very helpful, but I think he misses "to make the outer rim coarse".

Another guy has a similar idea and also posts a very helpful video.

Either way, both work very efficiently.

There has been a lot need to document, it seems that I need to start this part.

First of all, household main water shut off.

There are two main water shut off:
The first one is located by the meter and it needs a special tool to shut it off.

The second one is normally located inside, this video provides plenty of details.

Here some of the fixing videos

The second one is normally located inside, this video provides plenty of details.

My old video on how to fix the tub faucet.

My friend has heat pump issues and asks me for help, here are my homework and hopefully, I can get it fixed and update my note afterwards.

This guy gives five reasons that the thermostat can go black, I find it very useful and summarize the issues below.

1. Protection system kicks in the "shut off" the system, i.e. the drain pan is full of water
2. High voltage power issues, i.e. after power supply outage
3. Low voltage power supply issues, transformer's failure etc.
4. Battery fails
5. The thermostat itself fails

This guy makes the video thermostat wiring with heat pump system.

Good sources of videos

EdgeTek does a good job providing useful information.

Check the freon level

A common tutorial.
This one presents measuring in heat mode

The video gives clear explanation how the reverse valve can fail, and some important diagnosis strategies.

His initial video on basic heat pump operation, this is very helpful.

Diagnose the reverse valve.

My RAV4 is almost 4 years old, and it could be the time to start working on it with any error!!

Firstly, I found TPMS light on, after inflating all 4 tires, the light stays on!

Here, I find a forum site by Sam Leman on Toyota. Of course, it covers my RAV4.

Here are some ways to reset it:

	
Drive at or above 50 mph for 10 minutes. This can cause the tire pressure sensor to reset the next time you turn on the car.

	
With the vehicle off, turn the key to the “on” position, but don’t start the car. Hold the TPMS reset button until the Toyota tire pressure sensor blinks three times, then release it. Start the car, and wait 20 minutes for the sensor to refresh. The TPMS reset button is usually located beneath the steering wheel. If you are unable to find it, refer to your vehicle’s owner’s manual.

	
Inflate all tires to 3 PSI over their recommended amount, then deflate them completely. Be sure to include the spare tire, as it may have a sensor as well. Once they’re all deflated, re-inflate to the recommended tire pressure.

	
With the vehicle off, disconnect the positive battery cable. Turn the car on, and honk the horn for about three seconds. This will discharge any power still stored in the vehicle. Then, reconnect the battery.
