Re: Air flow sensor is saying that the blower is blocked
Try cleaning the air passages of the tv. you can try to do that using a small blower like the ones used in photography like the http://www.the-digital-picture.com/Reviews/Giottos-Rocket-Air-Blower-Review.aspx.

blower weak even any car made. answers.
a flow issue not a cold or hot problem , JUST AIR FLOW.
yes I just bore scoped mine yesterday, for fungus build up.
causes:
1: dampers bad, blend, recirc and mode.
Id say not blend as it will flow hot or cold or mixed.
recirc, will pick cab or , Cowl vent. parked will flow more in recirc.
leaving only MODE and blower DC power.
upper /windshield, mode,
the dash front mode<<<< this is best for the test, or below.
and floor vents.
the blower wires and resistor block and manual control wires not burned/ is this manual controls MTC?
do you hear blower sounding normal from before. when was good.
the bore scope is the cats Meow, so check all pathes.
on mine I can remove blower resistor block and use scope end
see vastly more things. insect nests/? leaves. , pine needles are th worst. and adds up. but if filter is there, this does not leave junk large past it.
I was worried mine, had fungus on right side of evap core but was wrong.
ok lets start with the codes they say your getting. P??? which 1's and how many. there are few o2 sensors, are they next to the Exhaust next to the converter? MASS AIR FLOW -MAF use this, for now i am guessing, until i see the correct codes your are getting. this could be the 1 you may have below, please read it........
Faulty mass air flow sensor
- Intake air leaks
- Dirty mass air flow sensor
- Dirty mass air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor circuit poor electrical connection
Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.
possible symptoms Engine Light ON (or Service Engine Soon Warning Light)
- Engine stall
- Engine running rough
- Excessive fuel consumption
- Excessive smoke
the code is generated when An excessively high voltage from the sensor is sent to Engine Control Module (ECM).
A sensor is saying ". . .airflow is blocked. . " Blockage could be the air filter or trap or ducts within the dryer or the 4" flex duct attached to the back. First, remove the 4" duct and see if there is good air flow with dryer running. If so, ream the duct all the way to the outside. If not, disassemble dryer to get to internal rigid ducting and blower. Also, make sure the blower wheel is not broken and can rotate freely.
Hello THECOOL The sensor is a freezestat sensing ice.Try a new air filter.Low air flow is a cause of freezing make sure the intake is not blocked and all the supply outlets are open.
Mine does the same. Sounds like you checked the air pressure switch, but the high temp switch and bad airflow can also cause this problem. Check the two white wires that lead to the heat sensor vent drain tube exits. Make sure the spade connectors aren't shorted. Try testing the temp sensor like you did the pressure switch to make sure the circuit is properly closing when in use (or use a temporary jumper to bypass as a test.) Check the bottom of the pan for any dust or crud that could block the airflow below or around the burners and last of my options- increase clearance around the unit to aid air flow.
"air flow blocked" means its getting too hot. or it thinks it is. it is quit common on these set that the thermal sensor has malfunction replaceing this sensor is your solution. since this is service bulliteen item at service centers of mitsubidshi products this may be an item covered under warrenty. so i would first check with you local service shop too see before
i had the same problem, much money spent for nothing, it ended up being the temperature sensor on the side of the block, advance auto, had the part for 10 bucks,
it sounds like there is no air flow check outside of home where vent exits house there should be strong air flow it either a blocked venting or a bad blower fan in the dryer most likely blocked venting start outside then work your back to the dryer if no air flow outside remove venting from the dryer ifgood air flow here the vent is blocked if not blower fan most likely broken these blower fans drive hub round out on the motor shaft of the motor but it would be very loud this should fix it for you thanks kevin
AIr flow is blocked?.....is this the message you get on screen mitubishi have a problem with what is called the thermal sensor.. the processor says its getting to hot... mitsubishi suggest service center replace this thermal sensor.
