Im looking at buying an LG fridge with the double doors and freezer on the bottom. It also has the ice machine and water hook ups but it needs a gas refill how much will that cost?

I wouldn't buy any modern fridge that needs a gas refill. Needing a refill means that it has a leak. Modern fridges are 'sealed unit' compressors and should NEVER leak. If they do then there is a leak, often in the evaporator coils inside the fridge and commonly between the copper to aluminium joins. These leaks would need to be repaired however most piping is not easily accessible. Cost may be $100 to $300 for re-gas plus repair $$$ and unless the leak was located and repaired then you will be re-gassing again in days, weeks or months.
LEAK needs FIX LEAK and re-gas.

Was working then made a raspi noise now nothing works

Sounds like you might have a problem with metal in the oven. Look inside the oven including the "ceiling" and see if the finish has worn off, leaving bare metal. If so, wash that area thoroughly, dry, sand lightly. Then apply some appliance paint that comes in tiny bottles and costs about $4.

repairs are always iffy and as the cost of a new card is low it would be better just to buy a new card.

Purchase msh09tw

Just so you know, you can use just about any condenser coil as long as it uses the same refrigerant as your original system does and if it will physically fit and has the capacity of the old one. However before you go out and buy something have you tried fixing the leak in your condenser coil? If it is made of copper then it is easy to solder with silver phosphorous and using a presto-lite torch. If you don't have one then you might try using map gas. As long as you can get 1,000 degrees or more it should work.

Good luck

Simply put, burned voice coil. Either too much power can do this or not enough power with distortion. solution- if the sound is clear then its too much power- turn the amp down. If the sound is distorted and raspy- its not enough power and your getting distortion-get bigger amp.

How do i get to the voice coils in my rockford fosgate 10inch p3d2. if that is not accessable where can i buy the back cap that covers the magnet?

I've never seen a question like this before. The voice coils are the copper wire wraped around a tube. This tube is connected to the cone and the spyder. The copper wrapped tube in is the middle of the magnets over the pole piece. Why you want access to them is beyond me. If they are blown there is no way to repair them. You cannot purchase the magnet cover separately. The only thing I have seen in my 23 years in audio is reconing kits. Sorry, it's probably not what you want to hear. But it was an interesting question.

It does cool the house but not as cool as normally does. Takes quite awhile to reach 70 degrees. Have turned off and back on again, turned off and washed outside box and has a new air filter in it also....

You can also buy some coil cleaner and clean the A coil. You can get coil cleaner from most hardware stores. The A coil on a split unit is inside the furnace look where the air conditioner copper lines go. there should be an access panel you can take off to get at the coil or you can access it thru the filter area. You will make a mess so have old towells ect... If its a combine unit where the blower is outside you can access it thru the side the air handler side of the unit. Usually you have to take the panel off on the opposite side of the unit from the external fan that is on top of the unit. When you find the A coil it will be obviouse it will be a radiator looking thing that usually is shaped in a A design. But if your unit can maintain 70 degrees now while its been around 100+ here it is doing a good job. Also look for leaks in duct work. good luck

Where can i buy second hand parts for the proform 590hr? I can buy the part i'm looking for £101, looking for cheaper thanks

If your looking for a inductor for your unit it would be unwise to replace this component with used.Since this device keeps current flow at a constant for your drive motor, thus generating heat in these inductors the copper wires are coated with lacquer. Thus over time causing the lacquer to crack and expose the copper wire thus shorting out and further damaging your unit.

the rottem electronic smell is the voice coil burned up as well as the bad sound, isn't the 1st time i have seen a JL sub blown. not worth fixing buy a new one the cost is not that much more repair on them is 250 - 450 depending on how bad it is and only JL can do the repairs as they dont authorize repair shops access to their voice coils. however i can sell you a new sub with full JL factory warranty drop shipped to your door for about 475$ or I could do you a way better sub ( the baddest competion sub made in the last 5 years) an olympus 2412 dual 2 ohm 5000 watt monster that has user replaceable voice coil options and is killing the competition circuit right now for about $275.00 shipped. it will stomp 2 13 w7's into the ground all day long. 2 subs vs just 1

you are probably actually looking for two 16v capacitors, not 25v. They are either black or brown near the huge copper coil magnet capacitor at the end of the board. A thin, tall metal heatsink sits between it and the copper coil capacitor. Philips is notorious for their completely worthless stereo systems, so they probably knew about the problem with the capacitors and put in 25v for later versions of the hts3450.
