COMES ON AND IMMIEDIATLEY SHUTS OFF

There's a problem on the power supply board. You can get parts here:

Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

What light is flashing Red? Is it on your thermostat or is it a red light inside the package unit at a circuit board?

Without the make and model number of the dryer, this is pretty hard to diagnose.

It could be relays, the main motor, or even the circuit board if it is a modern fancy electronic dryer.

one or two of the capacitors are weak over heating,or it can be something else like the power board.

sounds like power modules blown a capactitor or two or format board is overheating due to too much dust...remove cover panels and clean out dust from inside fans and circuit boards and try again....if this does not work may be the colour wheel or bulb

That model is famous for having issues with the deflection board failing. Replacing the deflection board should solve the issue. You can get replacement deflection board for the ITC222A chassis from www.tvrepairworld.com under the RCA circuit boards catagory.

Unplug it, wait one hour, take the back off, take a digital picture of all the cabling, disconnect all the cables from the bottom left board. The ribbon cables just pull out (they are firm though), Take the two wires off of the flyback transformer (you have to pull them hard). Release all the plastic tabs on the left, right and front of the circuit board and lift the circuit board up, release the two small black tabs in the middle of the board. Take the board to a t.v. repair shop, have them replace the bad capacitors/resistors/transistors. Pay them $35.00 Put it all back, hook it up and viola. That's what I did and it worked beautifully.

Does the LED blink? If so cont the blinks and let me know what it is.
