Sounds like the fan motor has reached its endpoint. It will have to be removed and replaced. Find the dircuit breaker in your electric panel that supplies power to the air conditioner unit. When you have found the right one, even the humming sounds will be absent. The fan usually is at the top of the unit. You must have opened this to change the capacitor. Remove the fan band motor as a unit and take it to a store like Grangers and determine if they have a motor that would replace the one from your unit. If the motor has a model number on it, you may find a replacement available onlilne by Googling that number and the name Amana. Put electricians tape over the wires that led to the motor, just in case someone turns on the circuit breaker before you have completed the job
Try to reset the memory on your HP Officejet. Do the following:
Turn off the power to the HP Officejet and unplug the power cord.
Hold down the "# + 9" button.
Reconnect the power cord and continue holding the button for another five seconds.
Turn the HP Officejet on, and the memory should be reset.
If this won't work, you can try to upgrade the firmware but you can only do this if the printer is still detected by the Computer. You can check control panel and see if the printer is listed as "online" or "ready".
If the above steps won't work. Your printer is deem defective and needs to be replaced. You can try calling HP support for more info. Here's their US number: 1-800-474-6836
The thermostat is not shutting the unit down and cycling it on/off as it should. This will cause the power cord to overheat and it will catch fire. STOP using this unit and either replace it or have it repaired. More than likely cheaper to just replace it.
Hi. The unit is programmed to not operate,or heat, when there is a serious fault within the door latch assembly. This F-9 code, represents a failed door latch assembly. This device must be replaced. Once replaced, the unit will operate correctly.
NOTE_ Try to reset the mechanism. This can be done by shutting down the power, or unplugging for five minutes. Once the five minutes have passed, simply, re-introduce power to the unit, and observe. if the error code returns, replace the door latch assembly.
In order to fully answer your question, a number of needful things must be inspected, reinstalled, confirmed, & tested:
Reset. Try the reset button. You could use a paper clip to reach the reset button through the pin hole in the lower front left of the Zonet KVM unit.
Inspect connectors. Each data/input/power connector/port requires all of its pins to be present & straight for full functionality.
Inspect the entire length of each cable & cord to ensure that each has no damaged area.
Seat each connector in the appropriate port of a computer that will be accessed via the KVM unit.
Electricity. Inspect all affected devices & confirm that each has sufficient, uninterrupted electricity.
It is possible for a Zonet KVM unit to display channel lights without direct power to the unit, but you should confirm that the unit is getting sufficient, uninterrupted electricity-directly through its own power cord. Unplug the KVM power cord & every connector & reseat each one (this performs a power reset on the KVM unit)-making sure that each connector is in the correct location (not just where it originally was). Thus, make sure that the keyboard, video display (monitor), & mouse are on the output side.
Press the power button on your monitor. If it does not turn off the monitor's power status light (Off/On/Standby), then remove the power cord from the monitor & reseat it-to reset the monitor's hardware. If it does not turn on the monitor's power status light, then the monitor is either not getting enough electricity or it has a malfunction which requires troubleshooting & fixing (possibly through a fixya.com thread for that monitor model).
Unlike USB devices, PS/2 devices usually require device connection prior to turning on that device. With that said, connect the keyboard & mouse KVM channel cable connectors to the computers & then turn on those computers that you intend to display through the KVM-connected monitor & then turn on these computers.
Any computer that does not turn on has an issue that requires resolving (just like a monitor that would not turn on).
Sometimes a keyboard/mouse interface issue can be resolved by replacing that interface device.
The KVM Unit. When all else properly connects & performs, what does not properly connect & perform has the issue &, hopefully, that can be repaired without having to replace it.
