If a brother printer wont turn on its usally a problem of the main pcb! Due to power or lighting strikes the microdevices might be shortcuted. Its cheaper to buy a new printer than to replace the board!

I have a Big Maxx heater and it won't stop blowing and won't heat. The fan just keeps running! Anyone know what could be wrong?


Your pressure switch may not be activating (ie closing and making contacts) This means you could have a blocked flue, clogged pressure switch tube or a bad pressure switch. The pressure switch is a safety feature to ensure your exhaust is not blocked and operating correctly. Find owners manual. Look at trouble shooting section. Open cabinet and look for error code light. If blinking 3 times, try "jumping" the pressure switch. To jump pressure switch you need to clear code be turning off power. When the unit/thermostat calls for heat the power vent fan starts first, this is when you need to jump the pressure switch. You need to do this in sequence. That is the unit first starts the power vent exhaust thus activating the pressure switch allowing the ignition cycle to the burners and heat. So the power vent fan needs to start first BEFORE you put the jumper on to bypass the pressure switch. Once the jumper is on it will call for ignition after approx 30 seconds. If ignites your problem is one of the 3 stated at the opening of this paragraph

Help me with my 1993 chevy cavalier 2.2L engine. My car won't turn on when ignition switch is in the on position. When I turn it to the on position, my radio cuts on, and my air conditioner turns on,...


what do you mean by "dash lights"? how do you KNOW the pump isnt working? how do you KNOW its good? at the ignition switch the ORANGE and PINK should have power in the RUN position the BROWN and TAN/WHITE should also be HOT in the run position. There should be a red wire near the fuel pump relay, make sure its HOT when cranking. IF its HOT and the fuel pump doenst run, the pump is bad. You can also put 12V on that red wire and power the pump.

How do I remove paper from paper jam?


To remove paper pull the paper with both hands being careful not to tear the paper . If you're unable to pull it you may need to manually rotate the gears that feed the paper through the printer
Now reset the printer by pressing the power button in on state to turn it off and restart
again thats all just take care that you remove the tray carefully

Thanks and Regards
