Advise on Defrost Timer

[moneycow]

Dear all,

My fridge a top freezer 2 compartment Toshiba model, I found lots of frost on the cooling fins of the freezer. The refrigerater bottom section is not cold. I suspect the defrost timer might be faulty.

Can some one advise if I can replace an alternative defrost timer to it ?

It uses this TMDF702ZD1

(Please see picture attached.)

and may I know what is the significant of the number 1,2,3,4 and some chinese words that indicates number.

Any advise would be grateful.

Many Thanks.

Dear,

Check your timer have a manual defrosting or no?
If manually you can rotate timer take it to defrosting method & and check the heater amp using clamp meter
If heater is taking some of amps may you can replace your timer

Thanks & Regarding,
