Strange noise from mk17

My MK17 first stage started leaking a little between the high pressure and low pressure joint of the first stage and made a strange squeaking noise occasionally. Now it only makes the strange noise very loudly and doesnt work at all. Any ideas?

It is a HORRIBLE idea for you to dismantle your first stage. It should only be done by a trained technician because of how many small parts there are... now depending on your regulator you might have the ability to turn down the pressure... read the manual to find out if your reg has this adjustment capability.

Press start and a whining noise happens


at the start the first thing that happens usually is the last water from the previous wash may be removed, so it could be the evacuation pump with little water in it, if this also happens at the end of the wash this would indiate this problem. the next thing is the water is taken onboard, due to model either the noise is from a pump that pumps the water in, or from teh water inlet, pressure which maybe to high or low. or from a aquastop shut off solenoid which has to be open, but usually they make more a buzziing noise when they have a problem. first check would be to ensrue your water pressure is ok then take it from there.

i hope this was useful.

2 Stage Furnaces More Comfort and Save Money


Two stage hot air furnaces can save you money and make your high efficiency furnace even better. With your furnace running at low fire instead of cranking up to the highest heating output in mild weather you can be more comfortable while saving money.

Many people think that they are getting the best they can get by buying a high efficiency single stage furnace. What they often don’t realize is that they could do better yet and for a few dollars more have a high efficiency 2 stage furnace that could keep them much more comfortable.


There are 2 stage hot air furnaces that are now available that will only run at half fire if the full fire is not needed. With a two stage furnace in mild weather when only a little bit of heat is needed, the furnace will have longer run times on low fire. This will keep you room temperatures from getting too hot before the thermostat reacts and shuts the furnace off again. This will help to keep your temperatures from overshooting the set point and help to keep your home much more comfortable.

Many of these two stage furnaces also have variable speed blowers that run at a lower speed when heating on low fire. This will also help to save money on your electric bill, because these blowers use very little electric when running at these low speeds. Air noise from the blower running at a high speed is also reduced.

If you are thinking of replacing or installing a hot air furnace, make sure that you ask your contractor to give you a price on installing a two stage furnace. The price difference probably will not be much higher than a high efficiency single stage furnace. However the comfort of the two stage furnace coupled with the electric savings will make the extra money well worth it.

1999 Sebring Convertible Air Conditioner is making noise


Well it could be a blockage in the system, but the high pressure switch should cut power to the ac clutch.
You checked both low and high lines and the high side was off the scale, or the low side ? Normal low is 30-45 psi and normal high is 200-300 psi.

Goodman model GMH95 no high heat


Some questions for you, did you adjust the Low stage gas pressure first and is is about 6" W.C.? Then did you adjust the High stage and is that about 10" W.C.? If the gas pressure is correct and the dip switch is on 2 stage, the unit should fire on both low and high fire for about 5 seconds then drop to low stage. If it does not, check the hoses going to the pressure switch for a leak. Test the high pressure switch when the unit tries to go into high stage to see if it is closing. Do not blow into the hoses or you will need new pressure switches. If it proves a closed switch, you will need to check for voltage at the gas valve. If you get none, replace the circuit board. If you get 24 volts at the orange wire hooked to the Hi side of the gas valve, you have a bad gas valve.

With inhalation there seemed to be a brief stop in the air stream and some resistance. This happens regardless of how my second stage is tuned. I have had two other divers to try it and they both felt it...


Hi,

Is this reg new by any chance??
Or perchance it's due a good service?? Sounds like something is sticking inside..

Alternately, I had a similar problem with my mk25 just after I bought it. The dive center I was in were able to fix it overnight for me so I the weekend wouldn't be a washout and the said afterwards that the problem was one of the seals/valves inside that was a bit of a design flaw. They knew about it and had replacements on hand so it could be worth letting your local service center look at it and see what they think..

It's possible this is it too..

Water trickeling noise from the compressor area.


If there is a leak in the system you will notice considerable change in temperature of the frig. In most cases, if this is a leak, you will see a builup of oil coming out of the leak as refrigerant has oil in it. You may be able to hear it or smell the refrigerant. What is commonplace in alot of systems is this noise. When the compressor is running, it is biulder pressure inside of the refrigerant lines. There is a low pressure side and a high pressure side while it is running. When the compressor shuts down after achieving the set temp, The system will start to equal the pressure on both high and low sides of the system. Actually the compressor will not start again untill these pressures are equalized or at least close. The noise you are hearing is most likely the refrigerant in the system while the system is equalizing the pressure on both high and low sides. I have noticed that some systems are more noticable than others. Unless you notice considerable change in temp of your frig, it is probably the equalizing of the system. I am not sure what the corrosion on the line would be without actualy seeing it myself but I have never come across a frig that had a leak and didn`t lose all or enough of the refrigerant without it being noticable inside the frig itself. For it to be a leak the temp in the frig should be or very soon will be noticably warmer.
