I have a viking range hood and the blower has stopped working. the motor hums when the switch is on but no longer runs the exhaust fan. I plugged it directly in to test if the switch was the issue and it is not. Do I need to replace the whole blower fan assembly? model number on the blower assembly is pv300001.

Hi if the new part has no screw holes or place for clip and it is only push in connector ie you dont need to solder the wires to it then it will just pull out use a small screw driver under the edge and gently pry free you cant damage it anymore than it is anyway can you.
Also on the side of the new switch if their is no groove cut into it for a push on clip to hold it in place then it will just pull out and push the new one in.

think i would call viking back and ask for refund of inspection fee and go by the bad switch scenerio the electrician said new fan that would be considered flaws in workmanship in most states dont know where you are located but pretty much same anywhere most inspectors for these companies always try to blame problems off on installers hold your ground and make them fix it and refund that" inspection " fee I've been doing electrical work for several (20+) years it takes longer than 5 minutes to troubleshoot something like that good luck

I also have this rangehood and have found out that this "Masano" brand is actually from a group called Nationwide Electrics or Electrical. They put out a lot of appliances with different tag names. Try googling for them and you may have more luck. I did find an appliance store that sells the Nationwide Electric rangehood identical to the CXW 200 in Cairns, so there must be others around Australia. I hope this helps.

I did some more troubleshooting and figured out how to get the plate off that houses the switches. I disconnected the fan switch and created a safe electrical by-pass. I re-connected the main power supply and sure enough, the fan worked. Issue = defective switch. Currently looking to order replacement. Problem solved.

Unless they start working again after it has a chance to dry out the touch panel will have to be replaced. This happens when excess moisture gets between the very thin layers of the membrane.
