I would suspect your "green" concoction got into the lint that "lives" inside the machine. Unbeknown to you, dryers have a lot of lint inside that is never cleaned, it just builds up.
In the last 20 dryers I have repaired, about 10 had a shoe-box or two full of lint inside.
Perhaps the mixture you added made mildew or mold accidentally in the lint nest.
Also, if you are in a complex and you'all have shared exhaust, perhaps it is someone elses problem.
You could take your dryer completely off the circuit and close off the "shared" vent system.
Then , see if that makes any difference.
I suppose you could also try to run your dryer inside your condo for 5 minutes to see if the smell is coming from your dryer when it is not hooked up to anyone elses.
If the smell is from yours, you will need to completely dismantle your machine to get every trace of lint and smell out.
God bless your efforts.

The unit was running when we came in. No Storms in the area. it was blowing hot air, but was still on the cool setting. There was a burnt wire smell coming from the unit. And the diag. code was Br. I found this odd since it still had power.

Have your ac man come and clean your coil on the unit.The smell may be trapped there.

There are a couple of things that can cause this odor. But, being sure it's really a gassy odor is more important. It must smell like "rotten eggs" to be gas. If that is the odor you're smell, turn the heater of and contact an authorized Rinnai dealer for service.

If however the odor does not meet the "rotten egg smell", there are other things that cause the odor, but it's not really from the heater.

If you have painted or stained within the last 2 weeks, the heater has picked up the odor of the fumes (which you probably didn't notice) and has made time 50 times worse. The same holds true for carpet cleaning or new carpeting odors. If this fits the scenario, discontinue using the heater for a week or two until the odors subside. In the meantime, if weather allows, air the house out. Also, remove and clean the heaters filter, before restarting the heater,

I hope this helped you to troubleshoot & solve the problem.

have any actually flushed the drain line to be sure they are for sure clear and open , and is the trap for the drain installed as per mfg reccomendations , sound as if some of the condinsation is remaing in the drain pan of the unit

when you smell something like that it only means your unit is leaking.the freon/refrigerant is what you smell.so i suggest compare a brand new one with the labor cost for repairs in your area.

Change your filter.

I have a maytag ac unit that kept smelling moldy. We tried spraying with antifungal, only helped for a short time. I took the unit (ac unit slides out of window case) outside and carefully removed screws only to discover the fan was covered in mold!!!! Oh my what a horrible discovery! I washed the fan blades with bleach and water mix. I completely and carefully washed and wiped down the air conditioner careful around the control box. Then I let the unit sit outside in the sun untill completel dry. Good bye mold and fresh clean cool ac!! I will do this each year now that I saw that ugly mold!! That is definetly a health hazard! I would reccommend you either thouroughly clean your unit or pay someone to do it or get a new unit right away!! Don't use that moldy unit another day!! Good Luck!
