Humming and failure to dim

Could be the ignition switch, could be the ignition relay, or could be the starter solenoid.

Transformer hum with dimmers is a problem. Lutron may offer you an inductor to add to the wire to help. Replacing your 50w bulbs with 12w LED bulbs may help, too. Same light output.

Ether bad compressor our bad start kit on compressor.

The humming would be the fuel pump coming on. It should only hum for a few seconds, then shut off.
Your problem is with the start circuit from the battery to the starter, or from the ignition switch to the starter solenoid. Check the connections at the starter (the big cable) for tightness.
Is the battery charged up enough to turn the engine over? Check by turning headlights on and observe while someone turns key to crank. If they dim a LOT, then either battery is too low, or the starter is bad and needs removing for testing. If brightness doesn't change, then the circuit from ignition switch to starter solenoid is likely not working. Check for 12 volts at the small wire to starter solenoid with key in cranking position. If you have power there, the solenoid may be bad. Remove starter for testing. If no power at solenoid in starting position, then either the ignition switch is bad or the neutral safety switch might be the problem, or the wiring from the switch to the starter solenoid is not passing current.
Good luck.

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.

Hi
Try Jump starting the car.
Looks like you have drained the battery. if the light are dim. that's a sign of week or discharged battery.

Base from the description of your problem this is a sign if a hardware failure already on your router meaning router is already dead, what we can try to do here to revive the router is to do a hard reset on the router.
Follow this in resetting the router using a pen of paper clip you need to press and hold the reset button of the router for 30 seconds while power is ON and after that power OFF the router for 10 seconds and power it back ON and then check if all the lights are still the same if still the same the router is already bad and if its still under warranty have it replace.

The humming noise and dimming of the lights is an indication something in the outdoor unit is locked up or has failed.

Check the capacitor as it may have gone bad. If the capacitor is good, then you either have a failed motor, a failed compressor, or both.

one of three thing possible, the start capacitor on the motor is no good, the start switch inside the motor is faulty, or the motor and or pump is locked up. if you do not have the test equipment to check it out I would advise finding a motor repair shop.

Is it connected to a fan motor also? - most dimmers are for lights only - if there is a ceiling fan connected you may experience a humming sound from the dimmer
