    I have the same problem, all systems blow, but cooling has stopped. The outside unit is sweating by the pipes?

    I have a Honeywell minizone system and my purge light keeps blinking. I notice that 1 upstairs room does not seem to get enough air and all the other rooms upstairs get a tornado. Any help is appreciated.

I have a Samsung one ton ductless air conditioning unit. Unit turns on in cooling mode, but after 15 seconds system turns off.


It sounds like it is cycling on a 'low pressure' switch due to a loss of refrigerant. However there a number of sensor failures that could cause the same thing.

I'd suggest contacting a reputable service organization for service.

This is my heater unit and it says purge. It says when flashing purge zms sensor failure or no zms sensor is installed. It used to work fine then stopped


It looks like either the actual ZMS sensor needs to be replaced or the wires to it are shorted or open...check it out!

My microwave has stop heating up food. What is the cause?


There are several things that can cause this:
1. Bad high power diode failure (most common and usually causes a loud humming sound when it fails initially then never heats again)
2. Bad capacitor (open or shorted)
3. Stuck Magnetron oscillator (Makes a loud humming sound when the Diode and capacitor are known to be good.) / Magnetorn failure
4. Door interlock safety switch failure. (You should hear 3 clicks on most microwaves as the door just opens or closes... if your microwave light does not come on when the door is opened you only have 2 micro-switches and only hear 2 switch clicks.
5, Main control board relay failure / main board failure.

Those are the most common reasons listed in order of usual failures. Each one of the above possible failures has a different troubleshooting procedure.

Why does furnace overheat and the limit switch shuts it off?


Are you in the North East region of US?
For the pass 6 days I saw a lot of postings for furnace and humidifier failures.
Partly is because the weather but the root cause is lack of maintenance.
====
User think LIFETIME Electrostatic air filter is maintenance free.
That is not true.
It's wash-able and need to be handle with care.
Inspect the air filter and replace it..
====
Lack of air circulation cause the furnace frame from burning efficient (BLUE FRAME) to orange / red color.
Over time,the temperature sensor will be coated with carbon deposit and record a higher temp reading.
They circuit will activate the fail safe and not allow the igniter to start on.
In your case,limit switch shut itself off.
Here is a LINK to pictures of Weather King temp probes and sensors.
A clean filter and temp sensor will save you money.
Dial back the furnace to 65F until you can get hold of the filter and clean the sensor.
==== If the MODEL TAG is still in plain view then please post it on reply.
Please keep me posted on the fix via email.

PURGE LIGHT FLASHING


It is a discharge temperature sensor and should be located in the duct after the coil. It should be just before the bypass damper.

Goodman GMNT furnace goes into 'lock-out'.


The brain has to have constant verification of flame. If the burner ground is corroded then you will get the condition you prescribe.

Art cool keeps stopping


Try to unplug the unit or “off” after 10sec. “on” the circuit breaker and then start the unit.
But if the defect persist then you need a qualified technician. The below error may be the cause of unit failure.
- Out of range thermistor is also can also be the cause of tripping outdoor unit with matching blinking light same as low refrigerant.
- Dirty indoor and outdoor can also be the cause
Remote control units have diagnostic program in the
control, after 3 to 5 minutes of operating if the diagnostic
tools detect abnormal operation, then its shutdown the unit
to protect from damage. Thermistor sensor is one of the
parts that detect the operation of the unit. Out of range
or defective thermistor can shut the operation of the unit.
- If your indoor and outdoor is clean start the unit in cool mode and monitor the outdoor pipes. If your suction pipe is icing or dry then your unit is under charge, but if your suction is cold and sweating then the system is ok and sure that the thermistor sensor is defective.
- Out of range thermistor sensor in both return air and freeze up sensor can cause the tripping “off “ the unit. The resistance of both thermistor is 8 to 10k ohms, so can test by using ohm meter
