Norcold sweet smelling

My Norcold 1211IMT has a sweet smell that I can't get rid of. It's not ammonia but more of a sweet chemical odor. I'm thinking there's something rotted somewhere but I've cleaned it inside, cleaned the catch tray and drain hose but the odor persists. I'm thinking I'm missing a drain somewhere. Baking soda has helped but the stink still quite strong.

Freezer compartments or refrigerator? I suggest you pour a bit of Hydrogen Peroxide along any joints in the liners, and allow to disappate on its own.

As asked....freezer or food compartment?

1200 only has one drain...food compartment drip tray under Fins that drains into drip cup by burner area


And as suggested.......
Seams in either compartment can have 'liquids' from food stuff.
Hydrogen peroxide lightly poured around seams can disinfect
**Should bubble/foam ...then wipe with damp cloth and rinse clean

Thanks for the suggestion. The odor is only in the refrigerator section. It has some chemical odor to it making me wonder if there's some sort of leak in the cooling system.

Leak in cooling unit is Immediate....not slowly over time

Cooling Unit is under 300+ psi

Leak...fridge would stop cooling down
Freezer & food compartments temps would increase and not come back down

Inspect the backside of fridge via outside access panel

Coolant is ammonia. It definitely does not smell sweet.

I've seen threads and other forums about a sweet smell in Norcold RV refrigerators. Some suggested checking the condensation drain line, to make sure nothing crawled up in there and died. I wonder if it might be the foam insulation they used? Decades ago I bought a Fender guitar case, and whatever they used on the inside of it had a sort of sweet/sickly smell that exists to this day. I think it's in the foam they used. Or maybe someone added some spray foam insulation around the sides of the fridge, and it's odor could be coming in through the condensation drain line? Or maybe they used some silicone caulk on the inside that's stinking it up? See if you can smell anything through the outside access opening.

The odor is not ammonia as it's been this way off and on for a couple years. It started after the previous cooling unit failed and was replaced. The smell is somewhat like melting crayons with a bit more chemical odor. I'm wondering if some of the plastic insulation was dislodged in the replacement and is melting a little. I'll see if I can find the electric heating element and check for anomalies.

Norcold 1211 uses TWO electric elements --- 225W each
They are inserted into metal tubes (holders) that are welded to the 'perk tube' (boiler section) and encased in insulation covered by sheet metal shield

The areas where HEAT would be present:
Burner area, flue/stack, elements and at top of Flue Stack where flue gases come out....and could impact side wall if RV MFG failed to properly shield/insulate
Old or New cooling unit they would not be in contact with anything that would melt...except for the insulation on the leads to the elements

How would the odor get into the refrigerated compartment? The freezer compartment doesn't have any odor. No odor is detected at the exterior of the unit. It does seem like something is melting but this has been going on for a couple years. One would think whatever was melting would have burned away by now. Definitely a puzzling issue.

Check the arear between freezer and food compartment


Divider Heater
The divider heater is permanently "foamed" between the divider separating the freezer and fresh food compartment.
The controls constantly monitor power board voltage output to the heater through built in diagnostics
Turning the refrigerator on automatically send power to the heater

Possibly the flapper heater in left door seal....pins/wiring on door and fridge frame etc
See pg 50 in Service Manual Link
