A homeowner in the Capitol Hill area of inner northwest Calgary reported that their built-in KitchenAid side-by-side refrigerator had stopped cooling properly, and that the problem appeared to be defrost-related. TechVill technician Hardeep confirmed that read with a meter rather than an assumption — twice.
Step 1 — Open the evaporator, look at it
Hardeep removed the evaporator cover in the freezer section and inspected the evaporator assembly directly. On a defrost complaint this is the only place the answer lives: the coil, the heater clamped along it, and the frost pattern on both.
Step 2 — Test the heater for continuity
The defrost heater read open — no continuity at all.
That is a definitive result, not a suspicion. A heating element is a resistive circuit; if a meter cannot find a path through it, the element is broken internally and no current can flow, whatever the control board commands. There is no interpretive gap between “reads open” and “has failed.”
Step 3 — Understand what that explains
Without a working defrost heater, the refrigerator can still run its compressor and still move air, but it can never clear the frost that accumulates on the evaporator coil during normal operation. The frost builds cycle over cycle until it packs the fins solid and airflow across the coil collapses. At that point the sealed system is fine, the fan is fine, and the cabinet is warm — which is exactly what the customer was describing as “not cooling properly.”
Step 4 — Replace the element
Hardeep installed a new defrost heater and reassembled the evaporator components correctly. The heater is a genuine KitchenAid service part sourced through Whirlpool Corporation’s parts network; the specific part number was not captured on the work order and should be read off the completed invoice.
Step 5 — Measure the new part, in place
This is the step that separates a finished repair from an assumed one. Rather than installing the heater and trusting it, Hardeep checked continuity across the new element after installation and read approximately 30 ohms.
Thirty ohms across a 120 V element puts it in the expected draw range for a refrigerator defrost heater — a real number, in spec, taken on the part as installed rather than as it sat in the box. The same measurement that condemned the old heater confirmed the new one.
Step 6 — Close up and check for consequences
The evaporator cover and all removed parts went back on securely, and the unit was checked over for leaks or damage before the visit closed. None were found. With the element live again, the refrigerator will enter and complete its defrost cycle normally.
The visit ran 110 minutes across all of that — cover removal, before-and-after electrical testing, reassembly and the final inspection — and carries a three-month labour warranty.
The invoice went down, not up
The customer had prepaid for parts at an earlier stage, covering more than one possible failure point. In the end only the defrost heater was needed.
Rather than retaining the balance, TechVill applied a $65 credit back to the customer against that prepayment and collected only for the parts, labour and service actually used. Today’s payment came to $469.35.
Nobody asked for that credit. The customer had already paid it, and would have had no particular reason to question the total. It came back because only one of the parts was used, and billing for the other two would have been billing for nothing.
That is the same discipline as the ohm reading, pointed at the invoice instead of the circuit: state what is actually there, not what was expected to be there.
