If you have a two stage cooling system, you are probably unaware of its turning the second stage on and off unless you are right there listening to it or have the proper tools with which to tell. Most of the times, it is just a higher speed that the compressor runs on with a change to stage two.

Many times, a two stage cooling stat is installed in a single stage system because that is what was on the service truck. If so, it will operate the same on first stage as a single stage will. Usually the tech gets into the setup and changes the configuration to make the stat believe it is only has one stage. Many people may think they have an option that's not there.

Just a possibility.

I have a Toshiba 32a33 TV, I have tried to program channels into the TV but it doesn't work. I tried to do it both manually and using the automatic channel tuner but it doesn't work. What should I...


Either the tuner or the video IF stage circuit of your TV is faulty. Tuner has no repair, can be replaced as a unit. If the fault is with video IF stage, it can be repaired. But, both the work is skilled one. You must have through knowledge in electronics, and work experience to do this work.

SAMSUNG HT X30 SHUTS DOWN WITH" PROTECTION"


It's a known issue with samsung Home Cinemas. It has to do with the cooling of the device and other related issues. One of the bellow could solve the problems.
First thing is to reset the device:#1 - Make sure there's on dvds in the system
#2 - Put it on stand by
#3 - Hold down the STOP button on the UNIT
#4 - HOLD until you see the stand-by light flash
#6 - This has now reset the system

If that doesn't work try to do a firmware upgrade http://www.samsung.com/in/support/detail/supportPrdDetail.do?menu=SP01&prd_ia_cd=&prd_mdl_cd=&prd_mdl_name=HT-X30

I am trying to install a thermostat and I am not sure where to put all the wires... it is for american standard freedom 90 two stage - furnace and air conditioning


Should be like this:

Y from furnace goes to Y on thermostat (yellow)
C from furnace goes to C on thermostat (usually blue)
G from furnace goes to G on thermostat (green)
W1 (first stage heat) to w1 on thermostat(white)
w2 (second stage heat) to w2 on thermostat (black)

Doesn't sound like you have a heat pump but if you do "o" will also have to be connected which is the reversing valve.

The speakers are connected but still no sound product is rd6613 sherwood


As always, you should refer to the manual FIRST before coming here. That is where WE will usually start.

I presume you have proven the amps are dead by trying multiple sources, swapping a different speaker onto it and that the balance control is NOT all the way to one side; headphones don't work either and we're down to proving it's dead before you take it in to a tech, right?

There is the slighest chance that a common control may have developed a high-resistance or 'dead' spot and is causing your symptom. Turn the POWER OFF and operate every control throughout its range a number of times, especially rarely-used ones like Tape Monitors and the MUTE control.

If it still doesn't work you might want to prove if its a low-level signal loss or a high level amp failure. One way would be to run an RCA cable pair from the Tape Out to any other device (even a TV with speakers) you might have that accepts an audio input. If IT can't detect receive the DEAD Channel you're losing it in the preamplifying or source selection stages.

If it CAN be played externally, the receiver is losing it on its way to or at the amplification stage. Further isolation might require hands-on technical expertise.

Our GE profile oven model JGsp31wet1ww oven will not heat up. When i set the oven to say 400 degrees, it just stays at 100 and never heats up. The broiler seems to work fine and the stove top gas burners...


pull out the racks and remove the bottom floor of the oven,turn it on bake,if the ignitor doesn't glow most likely it's bad,if it does glow and it doesn't ignite within 40 to 60 seconds the ignitor is bad.even though it glows doesn't mean it's good,it works by amps.it takes 3.2 amps.for a flat ignitor to open the gas valve and 2.5 amps for a round ignitor to open the gas valve.

What do two snow flakes on the left side of the control display mean on a Robert Shaw 9420 thermostat?


The double snowflake means that the second stage cooling is on. (One snowflake indicates first stage cooling.) This gives a greater temperature change in extremely hot conditions with than you could get with a single cooling medium and drier air in your home.
From the patent: A two stage cooling system in which the first stage's cooling affect is transferred to the second stage through direct contact with an oil-like material. The oil-like material is cooled by direct contact with water which has been evaporatively cooled. The oil-like material is then utilized to cool the air stream prior to the second stage evaporative cooling. The use of an oil-like material in the first cooling stage of evaporative cooling allows a relatively dry air stream to be produced so as to fully capitalize upon the evaporative cooling affect of the second stage cooler.

The second stage comes on if your system hasn't reached the desired temperature at the thermostat within a programmed length of time (5 minutes is a usual setting). BTW: Your system also has two stage heating.

I hope this helps.
