Yeah I have seen this in some tvs. If the tv has run for too long the fan continues to run till it sufficiently cools down.

    I am having the same issue... but even leaving the tv off for several hrs the fan continues to run and i would assume that would be plenty of time for the tv to cool down,

    Are you sure its the fan? The hum you have mentioned may also come from other sources such as the transformers on the power supply board. Can you please take off the back and verify if its the fan so that I can help you out?

Air handler fan comes on fine; compressor hums but does not start.


If you hear the o.d. unit humming:
•Check you breaker(s) both at breaker panel and at disconnect near o.d. unit if you have one.
•Behind the outdoor electrical panel, the part that is humming may have a bug/ants in it not allowing it to close. If so turn of all power(t-stat & breakers), clean points(where ants may be at the only moving part at the o.d. electrical), I usually use a little flat head, and try to start unit again.
•The run capacitor may be at fault. This component holds voltage and caution should be taken! This one is a round or oval part with wires connected to is, normally a metal or plastic body. If the top(where wires connect) is round/swollen or has oil looking stuff coming out, its at fault. Turn off power! Discharge by touching a screwdriver to the wire terminals at the capacitor to the metal cabinet. It may spark/pop if it discharges! Don't touch anything with you hands or any part of yourself. Replace with the exact capacitor it has on it(uf rating). Capacitors have been known to hurt people or worse!
Its always beast to call a tech. These 3 issues are the most common and it could be the o.d. fan has stopped allowing the compressor to over heat. Or a broken wire that allowed the unit to over heat. Work safe! And an HVAC tech is always the safest choice!

please follow this steps and fix it.
A fan failure, or a failure of the fan relay or control circuit is bad news because it can allow the engine to overheat.
Five things may prevent an electric cooling fan from coming on:
  • Defective temperature switch or coolant sensor
  • Engine thermostat is stuck OPEN (engine never gets hot enough to turn on the fan)
  • Failed fan relay
  • A wiring problem (blown fuse, loose or corroded connector, shorts, opens, etc.)
  • Bad fan motor
ELECTRIC COOLING FAN QUICK CHECKS.
One way to quick check the fan circuit is to start the engine and turn on the A/C to max. If the fan runs, the fan motor, relay, fuse and wiring are all okay. But this test doesn't show if the temperature switch or temperature sensor and PCM are energizing the fan when coolant temperatures are high.
To check the temperature at which the fan comes on, turn the A/C off and keep the engine running until it reaches normal operating temperature. Most fans should come on when the coolant reaches about 200 to 230 degrees. If the fan does not come on, something in the control circuit is defective. Resistance checks should then be made on the temperature sensor or switch, and a voltage check on both sides of the relay (you will probably need a wiring diagram of the fan cooling circuit on your vehicle to identify the relay terminals and wiring connections).
The fan motor itself can be checked by using jumper wires. Unplug the wiring connector on the fan, and use the jumper wires from the battery to route power directly to the fan. If the fan motor is good, the fan should spin at normal speed when supplied with 12 volts. Noisy bearings or a slower than normal speed would indicate a worn motor.

Toshiba 62hm15a blows lamp after 3months


One possible reason I can think of here is I think this model had a quick start or quick on feature.

What will happen if it does is set will come on and work normally--when you turn it off and watch the lamp, it will dim down but NOT GO OUT--AFTER 3-5 MINUTES THE FAN WILL (LAMP FAN) go off.

It was a stupid feature, lamp is running 7/24 at about 40 percent brightness--idea was you did not have to wait the 10-15 seconds for brightness to come up and be normal when set is first turned on.

If this is your problem look in the main menu for a setting like that and disable or deselect it.

Set when cold will take longer to reach full brightness and when turned off lamp will go completely OFF and lamp fan will continue to run for a few minutes.

I hope this is your problem---PS if the set is real dusty inside it can cause issues but that is rare in this set.

First of all, I replaced the lamp about 4 months ago, so it is relatively new. The Problem: The TV almost never turns on after the first try. The sound always comes on, the red light stays solid, but...


Some of these sets had a stupid feature. In the customer menu look for something called quick start.

The way you can tell if it is engaged is when you turn the set off the lamp dims but does not go out and the fans stay on all the time, clearly this feature was meant to speed up the turn on time but with it engaged when you turn the set off the lamp is still hot, if you turn it off and try to turn back on it will not function for fifteen or twenty minutes.

If you get the set to come on watch the lamp from the back and then turn the set off, does the lamp just dim down or go off? Lamp fan should run for a maximum of five minutes to cool lamp off, if it does not shut off and lamp only dims down look in the customer menu for quick start and deselect it, it is DEFAULT setting if set was unplugged.

These sets with this feature had problems where the lamp did not last two years.

Before you rate this solution let me know if you find what I described.

I have my dometic Rooftop ac unit. The heatstrip/fan run perfectly but when I turn on the ac...the fan runs good but when the compressor kicks on it just hums.


The compressor coming on does make a slight "humming" sound which is normal. Is the unit cooling properly? Do you think it is louder than before?

Overheating Problem with 2003 Bonneville. I have


The one thing I would check first is the cooling fan a quick check is with engine running turn a/c on and see if radiator cooling fans are running, if they are then we know the the fan's are good, if they don't come on check voltage at cooling fan if you have voltage bad cooling fan, turn car and a/c off, start car again with a/c off and fan's should come on at about 220deg. if they don't come on disconnect coolant temp sensor fan should come on, more then likely bad coolant sensor, now if fan don't come on you'll need check check your radiator or have a radiator flush.

If the humming noise is coming from the attic it would indicate that the blower motor on the air handler is trying to start but the rotor is locked.

If the humming noise is coming from the outside unit and the fan runs but the compressor does not your compressor has a locked rotor.

If the blower motor is the problem the outside unit should still start as normal but you would have no cooling due to no air movement.

In ether case it sounds like you need to call a service tech to diagnose your system.

I have the same thing, mine is the cooling fan for the lamp. If the sound continues for a short time after you turn off the TV then this is the most likely cause as the cooling fan will continue to run for a short time to cool off the bulb. I have looked into replacing mine, the part runs around $50 but I can't say yet how easy it is to replace yet.
