Question about Jenn-Air HV363 Kitchen Hood
When button is pushed hood rises and then immediately lowers and shuts off. Sometimes it works normally ie; stays up and blower activates. Sometimes it rises and lowers twice before stopping. Any ideas? I tried adjusting the switch position but it is pushed all the way up. It almost seems as though it should go a little higher. Maybe it just needs a new switch. It's less than a year old but I can't find the receipt.
If y'all don't mind, I'd like to add a few things. Sbron, IMHO, you're looking in the wrong spot. Based on what you describe as the problem, it sounds like the upper limit switch is loose or electrically intermittent. If you look at the link Cerfer 39 posted on page 4, right hand column top, you'll see the schematic. In the top right portion of the schematic, you'll see 2 switches, one normally closed (N.C.) and one normally open (N.O). Their upside down in the schematic... the switch depicted on top is actually the lower limit switch and vice-versa. It's the upper limit switch (N.O) that I believe is at issue here.
See, when the hood travels to its upper limit, the switch closes and sends power to the speed selector and blower motor and the lower limit opens and kills power to the gear motor. If either of these limiters fail, your hood will do some wacky things... like what you are describing, but if I were working on it I'd focus my attention on the upper switch.
Know this...access to the switch assembly is difficult if you do this while it's still in the counter top. The blower housing has to come off along with the blower motor and air box cover.
I'd pursue a different course of action if I were you. You know it's less than a year old but don't have the receipt. No problem despite what they say... this thing could have been bought and sold 15 times during its 1'st year, but it'd STILL be under warranty! Even without paperwork. The model number and serial number contain the exact date of manufacture (I know that you didn't buy it the day it rolled off the assembly line, so here's hoping that the manufacture date is less than a year ago.) and is all you need Call 1-800-688-9900 (USA) or 1-800-688-2002 (Can) and provide the complete model and serial numbers and get the Maytag man out to your house. DON'T DO ANY REPAIRS ON IT YOURSELF!!! THIS MAY VOID YOUR LEGAL WARRANTY CLAIM!
If the manufacture date is more than a year ago (Maytag will be able to tell you the date, btw), I'm afraid it'll be out of warranty unless you can find the original receipt. If this turns out to be the case, write back and let us know and I'll get you the part numbers for the upper and lower limit switches...

I have studied the drawings for your Air vent. looking on Page 4 of the following manual, you will see how to adjust the switch asembly. Jenn-Air does say it could have been dislodged during transport or installation. The provide the instructions for adjustment. here is the URL to get the manual.
now go look at Page 4 and try the procedure. looks pretty simple.
