Question about NAD T773 6.1 Channels Receiver

Open Question

Nad T773 is not power up, no light on stand by mode

I rarely use my T773, I have it set up in the basement, where I found the humidity is around 70% in the summer. I have power surge protected, one day it just not power up, I unplug for a week then plugged back again, the standby mode light is on for a few second, and won't come back again.

SOURCE: NAD T773 Shuts Down in 1-5 secs

Your problem is a common symptom of loose connection or cold solder and cleaning problem this is the main caused of no sound or automatic shut off for how many seconds..Cold solder issues - each component is soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the receiver turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough. Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder". Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing.... Good luck: Regards, VOTIT

I've misplaced the owner's manual on a DEN 500 P. What is a good basement setting for Summer in Central Ohio? Is a manual available on line?


I bought a cheap digital humidistat at Walmart to keep an eye on the humidity in my basement. I hung it on the wall not too near my dehumidifier. I have found that the settings on the dehumidifier are misleading, but I found a setting that keeps my humidity between 40% and 55% (at around 70 degrees), as measured by the humidistat.

Prt of the problem may be a dirty or clogged air intake filter.

Turn the unit OFF and unplug, it before removing the filter to check and clean it.
You can ether vacuum it or if it's really dirty & clogged, wash it in warm water and mild dish washing liquid. Rinse thoroughly, shake off access water and allow it to dry completely, before reinstalling it.
Never operate the unit without the filter in place. As this could damage the unit.

Plug the unit back in and turn it ON. Try lowering the humidity extraction level now, using the arrow down button. For a very damp, humid basement application 35% is a good setting to start with for several days.

Hope this helped you and thanks for choosing FixYa.

There are 5 basic, but solvable reasons for what you described. Please pay particular attention to numbers 1 & 2.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the Humid-i-stat sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

No all of the above may apply to your circumstance, but keep them in mind for non water collecting problem. Thanks for choosing FixYa.

Unit does not work, we turn it off, then hit power, it comes on for abt 5 mins., shuts off and does not come back on. in basement and humid


Kathy, there are 5 basic, yet solvable reasons for what you described. Please pay particular attention to numbers 1 & 2.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If you have a manually
controlled unit (No LED Screen) set the humidity extraction knob on Maximum.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

I hope this helps you to troubleshoot & solve the problem. Thanks for choosing FixYa.

There are 4 basic, but solvable reason for what you described. Please pay particular attention to numbers 1 & 2. Also, keep in mind, basements stay moister longer than upper rooms.

1. The humidity extraction level is set to HIGH. Lower it to 32-35% and disable the auto mode.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate

Whirlpool DEHUMIDIFIER Model - AD70USS1 does fan NOT does not cycle off anymore in the low settings as it should


According to the Owner's Manual for your model, the fan will run continually, if the unit is set in continuous mode or if the unit is in defrost mode. Once the unit senses a rise in the humidity level, the compressor will start up again. Also, a dirty or clogged air filter will cause the fan to run more that it should.

Hope this helps you troubleshoot and solve the problem.

Dehumidifier automatic on and off function not working


Unless you live in a dry environment or place the unit in a hermetically sealed room, it probably will not turn off. As the air dries within the room, more moisture comes in with the air. As long as the air outside of the room is more humid than the room this will be true.

Thanks


I went back and rechecked. If the fan mode is selected, you can only set the fan at one of the three speeds. If you leave it in the fan mode, the dehumidifier will not come on.

Once the fan speed is selected, it will run at that speed in the dehumidifier mode. The fan will keep running, even when the dehumidifier (compressor) shuts down.

The only way to get it to turn off is to use the clock setting, which either selects how long it stands-by before starting , or how long it will run before going back to stand-by. DeLonghi calls it "stand-by," we would call it "off." DeLonghi calls unplugged "off."

I've never turned mine to stand-by, because it will never get my entire house down to 30% humidity (I have it where my air handler returns air to the basement). I live in the greater DC Metro area, where 75% humidity is considered extremely dry.

Apparently the normal mode of operation is fan on unless awaiting a clock start, or encountering a clock shut-down; either condition puts it into the "stand-by" mode.
