Appliance Diagnostics & Repair
Greater Boston & North Shore, Massachusetts
Modern appliances fail for reasons that aren’t always mechanical. Control boards, sensors, firmware, power quality, and communication errors now account for a large percentage of breakdowns. That’s where we focus.
Astonish Applications provides appliance diagnostics, fault isolation, and repair coordination across Greater Boston and the North Shore. We identify what’s actually wrong, determine whether repair makes sense, and coordinate or assist with restoration — without guesswork, upselling, or unnecessary part swapping.
What We Do (And What We Don’t)
We are diagnostics-first.
That means:
-
We identify the real failure before any repair decision is made
-
We don’t replace parts blindly
-
We don’t inflate repairs that don’t make economic sense
-
We don’t pretend every issue requires a full service call
Depending on the situation, diagnostics may lead to:
-
A targeted repair
-
Coordination with a licensed repair partner
-
A recommendation to replace instead of repair
-
Confirmation that the appliance is functioning correctly and no repair is needed
Appliances We Commonly Diagnose
Refrigerators & freezers (including smart models)
Washers & dryers
Dishwashers
Ranges, ovens, and cooktops
Built-in and integrated appliances
Smart / connected appliances with control or communication issues
If it has electronics, sensors, or software involved, diagnostics matter more than brute-force repair.
Common Problems We See
Refrigerator not cooling or cooling intermittently
Washer won’t drain, spin, or complete cycles
Dryer runs but doesn’t heat
Dishwasher stops mid-cycle or throws error codes
Control board failures
Power-related or surge-related damage
Smart appliance connectivity or logic faults
Many of these are misdiagnosed by quick-swap repair approaches. That’s why this page exists.
Our Diagnostic Process
Initial Assessment
Symptoms, history, recent changes, power events, and error codes.Targeted Diagnostics
Electrical, control, sensor, and mechanical evaluation as applicable.Root-Cause Determination
We identify what actually failed — not just what’s easy to replace.Clear Recommendation
Repair, coordinate repair, or replace — with reasoning, not pressure.Restoration or Coordination
We either assist directly or coordinate with a qualified repair provider when licensing or specialization requires it.

Why This Exists Under “Diagnostics & Restoration”
Appliance repair today overlaps heavily with:
Electronics
Automation
Control systems
Power quality
Software logic
This service exists because traditional repair approaches often miss those layers. Our background in diagnostics, automation, and systems restoration allows us to approach appliance failures methodically instead of reactively.
What to Expect
Honest answers
Clear explanations
No sales pressure
No unnecessary parts
No “replace everything” nonsense
If repair doesn’t make sense, we’ll say so.
Get Started
If an appliance is failing, behaving unpredictably, or throwing unexplained errors, diagnostics is the correct first step.
