There is a high limit switch in your air handler it may be tripping because limit is not staying cool enough, check your filter and make sure you have normal air flow and enough retun air, 144 sq inches per ton

Monitor model 1702FP wont start. lights keep cycling


Hello,

The flashing power and signal lights are caused by 4 bad capacitors on the main driver board. Here is a link to information showing where they are and how to replace them.

There are one or two capacitors that open in the power supply, sometimes it will have a bulge at the top, making it easy to spot.

We have a 24DMC split air conditioner and it will not start up. The green light on the wall unit flashes 3 times followed by the orange button flashing 3 times. Can u please help?


A repairman just left and the problem is, I think resolved. The solenoid on one of the mini-split units was malfunctioning. It was telling the units that it was open and functioning but was actually not working for one of the two units, and caused the main unit to shut down. Once the problem was isolated and the unit fed by the faulty solenoid was shut down, the other unit functioned perfectly. So we now have half of the cooling for the house, but better than none, until we can get the part and install it.

The printer flashes orange light five times, and green once


Probably your waste ink counter. Should be cleaned or replaced before resetting but usually you can get away with resetting once.
1. Start with printer OFF
2. Hold down RESUME and then hold down POWER
3. Release RESUME
4. press RESUME twice, then release POWER
5. let green light blink until printhead has finished moving.
6. Select functions below with RESUME, execute with POWER

0 presses - green light - Test Print (exit service for i960)
1 press - orange light - EEPROM info print
2 presses - green light - EEPROM initialise
3 presses - orange light - reset waste ink counter.

This also applies to the i550, i560, i950, i960

Mine does the same thing...


If the main light is flashing 10 times you have a door sensor problem. Might be the wiring to the sensors. Nothing else will cause this flashing of the main light.

Power is shutting down with orange light flashing on t


Hi, This is na very common problem with these Dell machines. I have found one of two things are the cause of this. 
1. Your memory warms up once system is on for a while and fails to make proper contact on all pins, focing system shut down (after which only a power disconnect will restart system).
Solution. Carefully remove memory moduls and wipe copper contacts gently with a damp cloth after which you can replace the modules firmly. make sure power to the system is uplugged during the entire peocedure and give the system 5 minutes after putting modules back (just in case moisture from wiping remains).
2. Your PSU (main power supply) is failing. Replace PSU (cost around $50 at local IT shop).
cheers
