Field notes
What failed, what we did, what stayed open
Each note is short on purpose: the store type, the problem, the work and what the store could do while we worked.
Grocery, 14 doorsCondenser fan, overnight
A fan motor seized on the roof at 1 a.m. Head pressure climbed and two cases alarmed before the night crew noticed.
Motor and capacitor on the truck
Cases back in range before the doors opened
Written report left for the manager
Grocery, five compressorsRack controller swap, store open
An old controller lost its settings twice in a month. We staged the swap circuit by circuit so no case lost cooling.
One circuit down at a time
Alarm routing tested before we left
Old settings saved to the store file
Discount store, two rooftop unitsWinter clean-out on the roof
Coils packed with debris and a fan guard rattling. We cleaned, tightened and read amp draws before the first hard freeze.
Coils cleaned, fins combed
Fan and motor readings written down
Roof drain cleared
Grocery, open multi-deckProduce wall drain and defrost
Water pooled under the case every morning. A blocked drain line and a defrost that ran long were the cause.
Drain cleared and sloped
Defrost termination reset
Floor dry for the next delivery
Convenience, three walk-insWalk-in door and evaporator
A beer cave door would not seal and the evaporator iced over. New gasket and heater, then a defrost schedule that fits the delivery days.
Door hung true, gasket replaced
Evaporator thawed and checked
Delivery days written on the schedule
Grocery remodel, two phasesNew condenser pad for a remodel
A remodel moved the cases and the machine room. We set the new condenser, ran the line set and kept the old circuit alive until cutover.
Phase plan agreed with the general contractor
Cutover on a closed night
Start-up readings in the closeout file
