I'm using whirlpool mastermind chrome split ac.. clean filter light started blinking so i cleaned and replaced the filters but still CLEAN FILTER light is blinking. please give a solution


If you didn't turn the Master ON/OFF Switch to OFF, before removing the filter. That is the problem. To clear the error message. Turn the Master ON/OFF Switch to OFF, unplug the unit, remove the filter and reinstall it. Wait 10 minutes, plug the unit back in, turn the Master ON/OFF Switch to ON. The controls should have reset themselves and the clean filter light should not appear.

Hope this helped you solve the problem. Please let me know. Thanks.

Clean light flashing on dishwasher


if you have a whirlpool/ kenmore dishwasher and the clean light is flashing 7 times then pauses and then repeats, it is a problem with the heating circuit.
follow this keypad operation: push the high temp wash, air dry, high temp wash, air dry. this will put the unit into a service mode and it will run a short diagnosis cycle. after it gets done, about 5-7 minutes, then it will reset and allow you to use the unit again.
make sure the water is hot enough at your faucet at least 120 degrees, and the door is getting closed tight.

I have a rennai energysaver 556ftr heater, and the filter and on light keeps flashing red, i've taken out the filter and cleaned it, but still the lights are flashing. what's wrong?


If you removed the filter to clean it, while the unit was ON, that may be the problem. Turn the Master ON/OFF Switch to OFF and unplug the unit from wall outlet. Leave unplugged for 15 minutes. Remove and replace the filter. After 15 minutes has elapsed, plug the unit into the wall outlet and turn the Master ON/OFF Switch to ON. The unit should have reset itself and reverted back to the original factory default settings. In which case, you can change the settings to what you desire.

Just remember to always turn the Master ON/OFF Switch to OFF, when removing the filter to clean and replace it.

Hope this helped you solve the problem. Please let me know. Thanks.

The projector turned itself off after couple hours of use and the Temp. red light came on. Power Light turned red instead of orange as usual. After 3hrs I turned it back on, cleaned the dust off the fan...


There are three temp sensor inside the projector and now your projector need full service but if the air filter becomes clogged with dust, the internal temperature of the projector will rise, the TEMP indicator will illuminate and the projector's power will turn off (the TEMP indicator will flash after the power is turned off) The air filter should be cleaned every 100 hours of use.
If you clean the filter with a vacuum cleaner to clean off any accumulated dust. then your projector working normally

Our PJ-TX10 projector is turning itself off


First, to rule out true overheating, clean any dust filters and air-access areas. There might be enough dust on the filter to cause a gradual build-up of heat which could trip one of the temperature sensors in the unit. I clean my projector once a week--There might be a cooling fan going bad--after a while, heat causes the fan motor to start to drag and slows down the air flow. Also, there might be a temp sensor that is shutting down the unit prematurely.--Rick

Clean filter message and unit shut down.


Listen for the fan and the panel should be there. clean any vents you can find on the cabinet with a dry soft paint brush.some times the temp sensor will go bad and do the same thing.

Arcoair central heat /air conditioning unit


The blower motor kicks on when there has been a 24 volt control failure.

This usually means that a limit switch has tripped.

Most likely that would be a high temp limit switch or a rollout switch.

First, make sure the filters are clean. and the evap coil is clean. If eaither are dirty/clogged, it will partially block airflow, causing the furnace to overheat, causing the high temp limit to trip.

A rollout switch typically trips for three reasons.
1 flame rollout into the burner compartment due to poor airflow.
2 overheating af teh metal plate the rollout is mounted to, due to dirty, old, rusted components.
3 a bad limit switch.

If your unit has an LED light, count the flashes and it will hepl popint out the problem.
(locate the wiring diagram/flash code list, and correspond the flash count, with the code.)

First, check filters.

OSD Message Panasonic PT-50LC14 Air Filter Needs Cleaning


I had the same problem and the stupid tv would shut off after 1 minute. We opened the silver front panel , took the bulb out cleaned it, took the cover off the grey box to the right and very carefully vaccumed the filter and wiped it off with a microfiber cloth. It works great now!!! Make sure you unplug your tv before messing with it.

Filter light keeps flashing


The light flashes after a certain amount of run time. It is a reminder to check the filter to see if it needs cleaning. Once you have checked/cleaned the filter and reinstalled it, press the filter button for 5 seconds and the light should go out.
