In the land of the blind, the one-eyed man is king
You said two of the three holes so we gotta be talking about the external air intake holes that pull air into the oven right? I'm with @djurodjakovic .... how are they getting clogged? From the inside would be my guess since getting them clogged from the outside would be near impossible.My Hoppers have been in RMA for over a month so I've been using my Focus Pro hard and it's getting plugged. I've had this happen before and Puffitup replaced it once for me already. I can't imagine they'll do it again and I've tried everything I can think of to unplug it. Two of the three holes are completely plugged and the last one is getting there fast. Anyone know of any tricks to clear the air path?
I've taken the screen off and tried unplugging the holes and with a pick, I've also tried canned air and that didn't help at all. All along I've been trying to run burn offs between loads.
I really, really want a plug in unit that can take my heavy use without going through so many batteries and without plugging up. I just can't afford one right now.
Reclaim and/or small herb particles could clog it from the inside I guess. Reclaim sounds more likely but you'd have to allow it to cook, right side up and drip into the bottom a lot. The bottom of my oven gets gunked up but no where near enough to clog it like that. I just pull the screen and clean it and I'm all good. Are you using any concentrates with it? Maybe concentrate could drip/overflow into the bottom.
If I'm reading this right burn off's wouldn't have helped much since the maximum heat would not be flowing down into the holes past the oven. Heck...a burn off with enough reclaim built up on the bottom might even cause the reclaim to liquefy more and drip into the bottom and exacerbate the problem.
I can't think of any way to unlcog those holes other than trying to heat to max temp until that oven and the unit in general is as hot as it can get and then blowing INTO the mouthpiece to see if you can blow the clog outward with the hot air. Unfortunately this could make it even worse.
