Hi im working on a performa he (same as the baxi 105 he and main 30 he and its showing an air pressure problem. The fan is running with 240v at it and 34 ohms across it, the boiler lights when i manually make the air pressure switch by sucking on the tube. Ive also changed the aps with no joy. The fan seems to me to be running a little bit slow even tho its spinning freely and isnt stuck at all and has the correct voltage to it, Any ideas?
Hi, do fans on all boilers do the same job. as I've seen multiple videos and some say the fan brings in air and mixes it and brings it up to the heat exchanger but some other videos say fans bring in gas from a silencer tube. so which one is it? thankyou
Great video. Wanted to ask if the fan speed is lower then it should be would that mean the gas rate would be lower aswell. How would you know if the gas valve is faulty or it the fan if you couldnt check the fan speed and the gas rate is low.
@@warriorsofwarmth I see. But on modern zero govner boilers as the fan speed control the gas valve would you get low gas rate if the fan speed is low? Also the 2 tubes coming off the fan. I'm guessing one pull air in and one pushes it out. How does that happen when they are both in the same fan only 1cm apart? Shouldn't they do the same thing? Thank you much appreciated
@@warriorsofwarmth So what is the manufacturers spec? as mine reads 30 ohms on a Main 24 HE Fan. So l was under the impression lower was better as long as not under 20 ohms min

Great info pal..sprayed mine with some wd40 worked a treat ..many thanks

If fan speed was low the pcb would detect through taco, gas rate would be the same but poor ratios

abdul hafiz the interface would show a fault, all boilers have target speed and actual speed
So was the 45 ohms a good reading within tolerance for this fan? looks like a Baxi or Main combi fan
Yes it was the Ohms reading should be plus or minus 10% of manufacturer’s specifications

@@colin5064 sorry that’s incorrect the reading r low as fan motor is fast, I woud expect ohms to b higher? Call Baxi service
@@warriorsofwarmth So l have conflicting info on this video at 4.00 mins plus any comment on this?
