My 2004 Ford Escapes radio wont work and it doesnt let me lock my doors when the car isnt running it also doesnt ding when the car doors are open. what is happening?

Hello Al,

Does your dash display a flashing "service soon" indicator?
Have you checked for fault codes?

You have a good battery, your ignition switch is powering up the vehicles dash board and the vehicle will start and operate normally....?

Any lights on the radio display?
Check for 12 volts on the radio power power? check for 12 volts across the accessory / radio position in the fuse box. No power but fuse is good...wiring issue in the harness.

Power across fused circuit no power to radio check radio's in line fuse...fuse good? ... radio bad or disconnected speaker wires.

Make sure all your vehicles grounding positions are clean and tight.

When you say your door locks don't work are your talking about the switch on the door or the remote fob?

Check your owners manual to check for any radio reset info.

Hi Anonymous, Randy here I 'll see if I can help you with your problem. By chance have you Looked under the hood in your engine bay on the fender there should be a black box, this is the Power Distribution Box it contains Fuses, Relays, etc. This carries the Higher load fuses and such. Please let me know what you find, Hope this helps and Good Luck.

Will not run no lights or anything


The most probable thing wrong is going to be a blown fuse on the control panel. To check for that, disconnect power to dishwasher by turning off circuit breaker ,remove torx headed screws from around the inner door,seperate inner/outer door panel,remove the plastic cover off of the control panel, and use a multimeter set to measure ohms and remove the 2 wires to the thermal fuse and check for continuty with ZERO ohms resistiance on the thermal fuse. IF the fuse is blown the meter display will show OL or the display will not change...if using a meter with a needle the needle will not move if the fuse is blown..if the fuse is good the display will show 0.00-1.00 on a digital meter and the needle will swing all the way to the right and stay there on analog meter. If the fuse does check to be good the most likely cause of the diswasher not running will be the door switches. Here is what the fuse looks likeoldtech2332_88.jpg

Good luck i hope i helped you to fix your dishwahser,

665.68601890 Acts as though it is not receiving power but breaker is not thrown. Is there an internal reset. Nothing responds - no lights, fan or microwave. Panel is black and non responsive

ther is on most microwaves a fuse inside usually located behind display panel located in a fuse block or will be on the control board itself.. normally a 20 amp fuse...try that first if not then make sure you have power to control and if so and no display most likely the display control board...
may luck out and be just the fuse though....good luck

LG Microvave just stopped all at once as if the power went out. Nothing will respond. I checked the outlet is fine.

you may have blown a fuse if there is no power display...the fuse unfortunately is located in control panel... it usually is either a 15 amp or 20 amp fuse... do not put a larger one in or a smaller. to test the fuse if you cant visible see it is bad you will need to ohm out and should get continuity ...if the fuse is good and you have no display most likely the pcb or board is bad.... good luck

No power to the display. Have changed fuse and

It is possible that the display is damaged, due to a steam leak in the machine, remove display and check for corrosion on board.

No power to display and will not run

it could of blow internal fuses. but my guess is contact electricity suppler for compensation. you may not get it . but its worth a try. or house insurance.

Rt2280 no power up, no display, standby light works

Might be the relay on the power board that stands up just behind the big transformer. I has a complete no power also, I shorted out the relay legs on the black one, it started to work again. I will probably replace it, since the problem started by the system shutting off randomly.
