How do I test the defrost thermostat?


Defrost thermostat is a temp control. To test it, it would need to be in ice water. When cold it is a closed switch or contacts (checked with a multimeter. When it gets above 50--55 degrees it will open the contacts. Another way, unplug refrigerator----safely hook a jumper wire across the thermostat leads by passing the thermostat and then put the refrigerator in defrost. If heater comes on the thermostat is probably bad. If still no defrost--- you may have burned out heaters. Once done testing this way make sure you remove jumper and tape all wires for a safe connection.

Take your starting modulator in for testing. Make sure a pat test is performed. Pat test are to see if bouncing down the road is causing problems.

Problems with my proform 397 treadmill


Dear Sir:

Please do the following:

To usethese instructions, you need to have a familiarity with electricity and aworking knowledge of a voltage multimeter. With all of these tests, USEEXTREME CAUTION!!! Never let the voltage ground directly to any part ofthe treadmill or your leads ground while you
are testing voltage.

1)To begin, set your volt meter to AC volts. We are going totrace the power from the wall outlet through the
treadmill to see where it ends.

2)
With the treadmill unplugged, test the wall outlet. You should have from 115 to125 VAC. Optimally, you will
have at least 120 VAC.

3)Follow the power leads from the power cord to the lead ends.With the treadmill unplugged, connect your
meter to the lead ends. Plug the treadmill in and check your reading. It shouldbe the same as your reading
from the wall outlet.

4) Continue this process with the electrical system, following theleads, as they pass through, breakers, fuses,
and the like.

5)Where the power flow ends is where your problem is. Sometimesit will be in a bad connection, sometimes
it will be in a shorted breaker or blown fuse, at times it may be as simple asa safety switch not working
properly, or it may be a major problem with a component.
5) In some cases, components work in tandem (i.e.- a controllermay need a signal from the console
computer to release voltage to the motor)
TESTING FUSES, BREAKERS, WIRING, AND SWITCHEST

1) One of the most common problems with power outages is problemswith fuses, breakers, wiring, or switches.
2) If your treadmill is equipped with a safety switch, set yourvolt meter to continuity. Touch your test leads together to make sure you
are getting a closed circuit. With the treadmill unplugged, back the leads offthe safety switch, usually near the upper display computer.
With the safety key out, test the switch. It should be open. Push the safetykey in. Your circuit should be closed. If this tests ok, move to
the next step.
3) While testing for voltage, you can unplug your treadmill andtest the fuses, breakers, and wiring harnesses. Sometimes a breaker may
have shorted open and not tripped. Test these components individually. You wanta closed circuit on all of themSincerely. God bless you. If you need further assistance, please reach me.

I have a Vision Fitness T9450 HRT everything works including the incline when i turn it on but the treadmill will not run, is this a motor problem? or is it a fuse? how can i check ?


Dear Sir:

Hello I hope that everything is o.k

Now I will help you, only thing is you need to know how to handle the DVOM(digital Voltimeter)


To use these instructions, you need to have a familiarity with electricity and a working knowledge of a voltage multimeter. With all of
these tests, USE EXTREME CAUTION!!! Never let the voltage ground directly to any part of the treadmill or your leads ground while you
are testing voltage.
To begin, set your volt meter to AC volts. We are going to trace the power from the wall outlet through the
treadmill to see where it ends.
With the treadmill unplugged, test the wall outlet. You should have from 115 to 125 VAC. Optimally, you will
have at least 120 VAC.
Follow the power leads from the power cord to the lead ends. With the treadmill unplugged, connect your
meter to the lead ends. Plug the treadmill in and check your reading. It should be the same as your reading
from the wall outlet.
Continue this process with the electrical system, following the leads, as they pass through, breakers, fuses,
and the like.
Where the power flow ends is where your problem is. Sometimes it will be in a bad connection, sometimes
it will be in a shorted breaker or blown fuse, at times it may be as simple as a safety switch not working
properly, or it may be a major problem with a component.
In some cases, components work in tandem (i.e.- a controller may need a signal from the console
computer to release voltage to the motor) so if you have a question concerning where voltage ends, email
us at doc@treadmilldoctor.com.
TESTING FUSES, BREAKERS, WIRING, AND SWITCHES
1) One of the most common problems with power outages is problems with fuses, breakers, wiring, or switches.
2) If your treadmill is equipped with a safety switch, set your volt meter to continuity. Touch your test leads together to make sure you
are getting a closed circuit. With the treadmill unplugged, back the leads off the safety switch, usually near the upper display computer.
With the safety key out, test the switch. It should be open. Push the safety key in. Your circuit should be closed. If this tests ok, move to
the next step.
3) While testing for voltage, you can unplug your treadmill and test the fuses, breakers, and wiring harnesses. Sometimes a breaker may
have shorted open and not tripped. Test these components individually. You want a closed circuit on all of them

instructions Things You'll Need
  • Digital multimeter or analog multimeter
  1. Using a digital multimeter
    • 1 Connect the test leads to the volt-ohmmeter. Plug the black test leads into the black jack marked "Com" or "Common" on the front of the meter. Plug the red test lead into the red jack marked "Volts/Ohms" on the front of the meter.
    • 2 Set the meter's function switch to "Ohms" and the range switch to the "R x 1" scale. If your digital multimeter is an auto ranging meter, you will not have a range switch. Instead, you'll have just a function switch because the meter will automatically select the right range for the quantity that you are measuring.
    • 3 Turn off the power and remove the fuse to be tested from the circuit. Never test a fuse for continuity while it is still connected to the circuit that it is used to protect. If the circuit still has voltage, the meter will be irreparably damaged. If the fuse is still in the circuit when tested it is possible to get a false indication that the fuse is good if the meter gets a completed circuit through other circuit components. To be safe, always remove the fuse from the circuit before testing it.
    • 4 Touch the black test probe to one end of the fuse and the red test probe to the other end of the fuse. It does not matter which probe you touch to which end because fuses are not polarized. You are checking to see if there is continuity through the fuse element. A reading of approximately 0.5 on a digital meter's LCD indicates a good fuse. Most digital meters read their own internal fuses resistance, hence 0.5 Ohms and not 0.00 Ohms. LCD readout of "O.L." indicates no continuity through the fuse. The fuse is bad and needs to be replaced

Thank you in advance, best regard. Blessing.

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your "((motherboard to your hard drive))" make sure they have a secure connection and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error

I need to check the monitor on my laptop to see if the connection to the motherboard is loose or if the inverter is bad.


Hi,
It can be hard to figure out a laptop monitor fault. Some laptops will give beep codes if the likes of the connection has become loose/failing. If the invert is gone and the laptop is booting ok you can sometimes see the desktop on the screen if you look very closely.If you can't it could be the bulb in the screen that has failed.
If your up for ti you could try testing the inverter. http://www.fonerbooks.com/test.htm

Skype sometimes working!


Hi,

Looks like connectivity issue, so it can be wi-fi dongle.
If any other pc/laptop has wired internet connection Or if you can wire-connect present pc/laptop then you can test using skype from it. If it works fine then wi-fi dongle maybe the culprit.

Also there are many sites for testing internet connection speed etc.
Test your internet connection using the dongle.
