Question about Coleman Heating & Cooling

1 Answer

Looking for a replacement thermalmite for a coleman drhq0301bd heatpump. Not sure of the name, but it is the ceramic component that is cylindrical, has a yellow wire attached on one end, yellow and brown wire connected on the other, and a red wire in the middle. This component is mounted just above the capacitor.

Where can I buy a capacitor, regulator and a craft shack for my Coleman 7500/9000

Sorry not sure what a craft shack is in the context of a generator.

Try an internet search for what you need. You are likely to discover genuine parts are quite expensive but items like the capacitor and regulator is likely to be bought in by the generator manufacturer so if the components have printed on them a name, a value, a part number; it is often possible to locate "genuine" parts from the original supplier.

I recently bought a start/run capacitor this way for a pressure washer and it cost me less than a tenth of what it would have done from the pressure washer manufacturer.

well if it's the wire that goes from the throttle pedal to the engine it's called the throttle cable assy... if it's not then you need to explain where it hooks up at both ends... or take pictures

My toshiba l300 freezes or switches off when i plug in ok on battery tho! ???

Suggest laptop has a problem with Power MOSFETs in the power section area of the motherboard, and/or MLCC ceramic capacitors that are nearby the Power MOSFETs.


Here's an example of the DC Power Harness;

[DC Power Jack is the jack on the laptop, that you plug the AC adapter (Charger) into.

For your model the DC Power Jack, is connected to wires that end in a plug. (Harness)
The plug plugs into a small white connector on the motherboard.
The DC Power Jack itself sits in a channel, along the outside edge of the Base Enclosure. (Bottom Cover) ]

Toshiba Equium L300 series of Notebook PC, motherboard general example; Top and Bottom views,

Scroll down to the Yellow 'frame', and click on the first photo shown,
[ Original Part - ebid-deaklz ]

Look at the Top Right corner, and at the mounting hole.
There is a aluminum looking cylindrical metal spacer below it.
To the bottom left of that cylindrical metal spacer is a white connector for a plug.

The plug to the DC Power Harness.
This is the power section.
Note the Power MOSFETs on the motherboard.

One to the immediate bottom right, of the white motherboard connector mentioned above, one above to the top left of the white connector, and close to the outside edge of the motherboard.

This is a general example of a Power MOSFET used in this type of application, and used in a LOT of laptops; (Not indicating this model is what your motherboard power section uses),

Note the eight J-leads used on both sides. (4 per side)

More information using HP Pavilion dv6000 series, and Pavilion dv9000 series Notebook PC's, as an example,

Note the second photo down with the Alpha and Omega Semiconductor - AO4407 - Power MOSFET, circled in Yellow;

To the immediate right of the AO4407 is a small rectangular object, with a dark wide band in the middle.
This is a Ceramic Capacitor.
(Multi-Layer Ceramic Capacitor, and Surface Mount Device;

There is one above it, one above that, and one to the right of the top one.

Now go back to the Top View photo in the Ebay link, and view the Power MOSFETs around the white connector, on the motherboard, for the DC Power Harness.
Also the MLCC ceramic capacitors.

If you see obvious signs of damage to the Power MOSFETs, or ceramic capacitors, such as burning, blistering, or blackening, they need to be replaced.

Or replace the motherboard.

In reality you do not know if the repairs you made 'will stay'.
Already burned out electronic components you replaced, may have taken out other components, or weakened them.

More logical is to replace motherboard, unless you are fine with opening the laptop back up again, and replacing the motherboard the second time around.

If you do wish to attempt repair, Power MOSFETs are about a dollar (USD), and ceramic capacitors range around 52 cents to 80 cents.

Take the Fairchild Semiconductor International - FDS6679 - Power MOSFET, for an example,

Toshiba satellite c655d motherboard componet x4701 blown

There are no fuses on the motherboard.

The X4701 may be a Macom RF Power MOSFET, and will probably be located close to the X4701 designation, silkscreened on the motherboard.
Doesn't EVEN look like a fuse.

This is a general example of a Power MOSFET,

Notice the J-leads on the sides.

I wonder if you are looking at a crystal diode, or an MLCC ceramic capacitor, (Multi Layer Ceramic Capacitor, and is SMD. Surface Mount Device)

(Scroll down)

At any rate let's look at a Satellite C655D series of Notebook PC's motherboard,

Under the large main views are small views.
The view to the far left is the Bottom side.
The third view from the Left is the Top side.

You have to click on each one, one at a time, then you can use the Zoom In feature for that view.
Using the Zoom feature, can you try to point out the electronic component?

Use a reference point we can both follow. State a known large component near it, and go from there.

You know what the processor socket, and graphics chipset is. They are covered by the Cooling Tube.
You know what Power MOSFETs look like now, and Ceramic Capacitors.
The small aluminum 'can's that have a purple mark on one side, are solid Polymer capacitors. (Doubt they are Tantalum)

Also, I realize that it gives one a sense of pride to repair a motherboard, and the cost of the electronic components are MUCH cheaper than buying a replacement motherboard, but a replacement may be the way to go.

(Fairchild Semiconductor International - FDS6679 - Power MOSFET is around $1.
Ceramic capacitors, (MLCC, and SMD), are around 60 to 82 cents.
From the Ebay link it looks like $39 to replace the motherboard)

Capacitor failure? Ehh. No problem if we're talking SMD MLCC ceramic capacitors.

Diode goes bad? Could led to power going to the wrong place, and other electronic components could have been affected.
Could be bad, or about to go bad.
Jus sayin'.

This would mean motherboard replacement is the more logical solution, IMHO.

I have a panasonic nw -h665 Microwave. 3 months old. It just does nothing. Fuse Maybe Blown? and where is it ?

3 Months old? Under warranty surely. Just call Panasonic Repair Service for a free repair.

There are fuses in there but they don't fail for no reason.

Where is the capacitor located on a coleman heatpump

If you're talking about the outside fan, look where the wire goes into the outside unit. The capacitor will be somewhere near the circuit board and will be round or oval and metal or plastic. If you're talking about the inside unit it will be with the electrical control in the air handler. Write down where the wires go. The terminals on the capacitor will be marked and for the outside unit you will either have 1 that runs both the fan and compressor or a seperate one for each. If you have 1 that runs both the wires must be reconnected to the right terminals. They will be marked COM, FAN, HERM(stands for compressor). Take the old one with you to get a new one. Let me know what you find.

This is actually a very easy task as long as you get a direct replacment board. If not the key essentials are the reversing valve contacts and the power contacts coming to the board.
As long as the board is a direct replacement you can switch wire to wire form the old board to the new board.

Please re comment me if you have any other questions.
