capacitor for carrier electronic air filter

[russ]

I have an old carrier electronic air filter # 31MP514110.
It stopped working and found a broken part (looks like capacitor in the power
supply part # TRW84840RB-4 30M15%)
Unfortunately nobody can identity this capacitor / part properly and digi-key
doesn't list this part

looks like a resistor to me.30 meg maybe?
lift one end and see if it measures ok.

Hard to say. It would help to have a picture of what its connected to... then perhaps one of us could guess what the appropriate replacement part would be based upon its application.

The blue thing is a high voltage resistor. If you carefully remove the crud on the remaining pieces, there may be a value. Most likely it will just be a Carrier part number. That resistor is critical to limiting the corona current in the air cleaner. I would also replace that capacitor just because of the age, since the value (change in value) will affect the high voltage output of the supply. These things are tough to fix without the right parts. Be careful of the h.v.

Clean the dust off the writing side. Agree its a resistor. What I can see with tweaking in Paint Shop agrees with kc8adu.

???.. TRW 8440 RB-4
???.. 30M 15%

The typical failure is the big cap.

part reads : TRW84840RB-4 30M15%"
