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

Compaq presario cq62 won't start but the caps lock led blinks continuously and the wifi led remains on continuously, tried new cpu, worked for a while and started same problem again.


those are blink codes, learn to count them.
if you pulled the CPU i bet you that you used the wrong heat sink compound.
The CPU shuts off all by itself if too hot. your job is to get the fan working and the heat sink working and that thermal compound right.

No heat till you start driving and then fan will kick on and not shut off but it doesnt overheat


You won't get heat right away. The heat has to have time to reach the heater core. That's where you get the heat for the passenger compartment. But if the fan isn't turning off, then I would have it checked for an electrical problem.

Fan will not work


mcdevito75 here, Most likely yes, Check the fan by carefully turning it just a liitle by hand, also check for heat at the fan motor base, close to the ceiling. If heat or fan won"t start by hand, replace it.

The heat will not turn on


If the fan is blowing with no heat, it is an indication you have an error code. Check the control board for a blinking light. If you find one, look on the wiring diagram that is pasted on the reverse side of one of the panels for a diagnostic chart. It will give you a starting point where to look for the issue. You can always jump the red and white wires on the thermostat and if the furnace starts, it's a bad thermostat. If not, look to the blinking light.
