ANY ONE HAVE A CIRCUIT DIAGRAM CAN SEND ME OR A LINK ? I NEED TO FIND OUT WHAT THE RATING ON ONE OF THE RESISTORS ARE SO I CAN REPLACE IT. IM NOT NEAR THE FAN RIGHT NOW SO THATS WHY IM ASKING

The colour rings on the resistor tell the ratings of it. Should be able to google a resistor chart.

listed under air purifier,send to manufacturer

I would look at the board using a high powered magnifying glass to see if there was any signs of broken stubs of wires sticking out of any solder joints. Also look for solder joints that have no other possible routes, (dead ends) that do not have any other connections running from them. Like a resistor that has a copper path on one end and nothing running from the other end. Or it could be a ground wire if no other spot is found.

i think it s worng type of blower resistor

I'm thinking it's the circuit board. I would call Vollara (they bought Ecoquest) & see if you can get a circuit board or send back to them to fix. 800-989-2299. Or, you can Google circuit board for Fresh Air & see if there are any suppliers that you can get it from.

Broken discharge plates have to be replaced, otherwise the high-voltage shorts-out through the break. The glue being burned is an additional clue.

The fan is a separate circuit/function.

Replace the glass plates (purchase from EcoQuest Intl. or from a EQI dealer near you, expect to pay ~$20-30/plate depending on model and shipping costs. I also sell them as I am an EcoQuest™ dealer, though the shipping charges may make me less economical than someone local to you. If you want my contact info, please respond with a "FixYa" rating - thanks in-advance.

If I can be of further assistance, or if you have questions about any of my response(s), please let me know before rating me.

If this solves the issue, please rate it accordingly. My goal is to earn a "FixYa" rating from everyone I help.

Thanks for using Fixya.com,

There is a problem with the main circuit board. Ecoquest will replace the circuit board. If the Fresh Air is still under warranty you have to pay shipping. If it is not under warranty, you'll have to pay all of the repair cost. You'll need to call to get an RMA number before you send it in, either way.

OK, good news and bad. Check the actual fan speed potentiometer with a ohmmeter. There are only two outs from the pot itself to the little circuit board that its attached too. The pot is 75K so make sure your ohmmeter is in the right range setting. With the meter connected, turn the dial and make sure it goes from 0 to between 70K and 75K ohms. If it doesnt or its all over the board, then the pot is the problem. Now I can't seem to find one that is a direct replacement, 75K is an oddball. I didn't un-solder mine from the board. If yours is bad, unsolder it and look on the back for the manufacturers part number, google that with the p/n as the search terms.

The circuit for the fan is not tied to the sanatize button. The circuit is relatively small, with two film capacitors, two resistors, a diode, and a triac. The circuit is on the board located underneath the unit. The circuit is located right next to the fan pot inputs on the main board. Its about 1" square with the "fan pot" inputs at the bottom left corner, if reading labels right-side-up. Resistors are almost indestructable so it is probably not them. I would lean towards the triac, diode, or caps. Look at the components and the solder connects in that circuit. If anything looks burned or black, or a solder joint looks like it has gotten too hot, that component is probably the problem. If its not the pot, which more likely than not it probably is, then I would lean towards the triac or diode. Here is the triac p/n:511-BTB06-600T. The diode I would also have to unsolder to access the part number, or I would list that as well.

I would start at the pot. That would be my guess as to what went bad. It could also be a bad solder joint on the small board the pot is soldered on to. Also check and clean the 1/4" disconnect terminals on the fan motor itself. For mine, I just cut off the old female terminals on the wires and crimped on new ones.
Hope this can give some help.

HI,

First of all please go through the user manual found in the bellow mentioned link:
