Question about Viking Professional VCBB363SS Stainless Steel Refrigerator
REPLY to "fixit 4 ya" - Checked continuity on heater coil using ohm meter and result was negative (no continuity). I guess the heater coil has a break which is why freezer is not defrosting. Is the defrost sensor the flat silver piece? How do you check if it is good? Ran ohm meter across it and its result is negative as well. I don’t know anything about refrigeration, but I’m guessing when the freezer builds up ice on the heater core the freezer temp either gets colder or warmer. Whichever it is the internals of the defrost switch will make contact and send current to the heater coil which then heats up and defrosts the ice. Once the temperature goes back to whatever the defrost switch is set for, the contacts will open thus turning off the heater coil. Is this how this system works? I haven’t read anything on defrosting so I’m just guessing.
SUGGESTION FROM fixit 4 ya -
Before replacing all of the components mentioned above, locate your defrost heater and check for continuity with an ohm meter,this will ensure no breaks in heater coil
Need photo of freezer defrost sensor, switch or thermostat Anyone have a photo, of the freezers defrost: switch, sensor or thermostat? Also, how to check if these parts are More
Anyone have a photo, of the freezers defrost: switch, sensor or thermostat? Also, how to check if these parts are working and how to order replacement part. Frost keeps building up even after manually defrosting. I removed the back plate and defrosted with a hair dryer twice now. After 3-weeks the frost builds up again. I have not seen any water in the defrost pan so the unit is not defrosting.
Unit needs to be cold when you test. it closes at around 20 or 30 degrees F and opens around 55 deg F
