The 5 Most Common Compressor Failures
Fix 1: GE Dehumidifier Humming But Not Starting? Capacitor Fix ($10-25)
| Element | Detail |
|---|---|
| What fails | Start capacitor or run capacitor |
| Why it happens | Electrolytic capacitors degrade over time, especially in continuous operation. The capacitor loses capacitance, reducing starting torque. The compressor attempts to start but fails |
| What triggers it | Continuous 24/7 operation, heat exposure, age (1-3 years) |
| What you’ll see | Compressor hums for 2-5 seconds, then stops. Repeats every 5 minutes. Unit runs but no water collection. Fan runs normally |
| What it costs you | Start capacitor: $10-20**. Run capacitor: **$15-25. Repair shop upsell: $150-250 for “compressor diagnosis” |
Your Decision:
| If… | Action | Why |
|---|---|---|
| Capacitor failed, unit otherwise fine | 🟢 REPAIR | $10-25 fix — always worthwhile |
| Unit is < 2 years old with capacitor failure | 🟢 REPAIR (warranty) | Should be covered |
| Capacitor failure AND unit > 5 years old | 🟢 REPAIR | Still worth it ($10-25) |
Fix 2: GE Dehumidifier Fan Not Spinning? Compressor Overheating Fix ($50-100)
| Element | Detail |
|---|---|
| What fails | Condenser fan motor |
| Why it happens | Fan motor bearings wear out, fan stops spinning. Compressor relies on fan for cooling. Without cooling, compressor overheats and thermal overload trips |
| What triggers it | Continuous operation, dusty environments, lack of maintenance |
| What you’ll see | Fan not spinning. Compressor runs hot then shuts off. Unit stops collecting water |
| What it costs you | Fan motor replacement: $50-100** (if caught early). Compressor failure: **$500-700 (if ignored) |
Your Decision:
| If… | Action | Why |
|---|---|---|
| Fan stopped, compressor still runs (hot) | 🟢 REPAIR | Replace fan motor ($50-100) |
| Fan stopped AND compressor failed | 🔴 REPLACE | $500-700 repair vs $250-400 new |
| Unit is < 2 years old with fan failure | 🟢 REPAIR (warranty) | Should be covered |
Fix 3: GE Compressor Seized or Refrigerant Leak? REPLACE ($250-400)
| Element | Detail |
|---|---|
| What fails | Hermetic compressor or sealed refrigerant system |
| Why it happens | Continuous 24/7 operation causes wear. Refrigerant leaks from brazed joints. Oil degrades from sustained high temperatures |
| What triggers it | Continuous operation, age (18-36 months), poor oil return |
| What you’ll see | Unit runs but no water collection. Compressor makes loud humming. No temperature differential between intake and discharge |
| What it costs you | Compressor replacement: $500-700**. Sealed system repair: **$350-650 |
Your Decision:
| If… | Action | Why |
|---|---|---|
| Compressor failed AND unit < 2 years old | 🟢 REPAIR (warranty) | 5-year sealed system warranty may cover |
| Compressor failed AND unit > 2 years old | 🔴 REPLACE | $500-700 repair vs $250-400 new |
| Sealed system leak | 🔴 REPLACE | $350-650 repair vs $250-400 new |
Fix 4: GE Dehumidifier Compressor Won’t Start? Start Relay Fix ($20-40)
| Element | Detail |
|---|---|
| What fails | Compressor start relay (PTC or current relay) |
| Why it happens | Relay contacts arc during each start. After 10,000+ starts, contacts pit and fail. Relay may stick open or closed |
| What triggers it | Frequent start/stop cycles, continuous operation (more starts) |
| What you’ll see | Compressor doesn’t start. No humming. Or compressor runs briefly then stops. Click sound but no hum |
| What it costs you | Relay replacement: $20-40 |
Your Decision:
| If… | Action | Why |
|---|---|---|
| Relay failed, unit otherwise fine | 🟢 REPAIR | $20-40 fix |
| Relay AND capacitor failed | 🟢 REPAIR | Replace both ($30-65) |
| Unit is < 2 years old with relay failure | 🟢 REPAIR (warranty) | Should be covered |
Fix 5: GE Dehumidifier Not Collecting Enough Water? Weak Compressor Signs
| Element | Detail |
|---|---|
| What fails | Compressor efficiency degrades |
| Why it happens | Internal wear reduces compression efficiency. Oil degradation causes wear. Low refrigerant charge reduces capacity |
| What triggers it | Continuous operation, age, oil degradation |
| What you’ll see | Unit runs but collects less water than before (30-50% of rated capacity). Humidity doesn’t drop |
| What it costs you | Recharge: $150-250**. Compressor replacement: **$500-700 |
Your Decision:
| If… | Action | Why |
|---|---|---|
| Low capacity, unit < 3 years old | 🟡 EVALUATE | Check filter, coils, charge level |
| Low capacity, unit > 3 years old | 🔴 REPLACE | Not worth repairing |
| Low capacity + no water collection | 🔴 REPLACE | Compressor likely failed |
Why Does a GE Dehumidifier Compressor Fail? Engineering Causes
Capacitor Degradation
Component: Electrolytic start and run capacitors
Mechanism: Capacitors lose capacitance over time due to electrolyte drying. Heat accelerates this process. When capacitance drops below 80% of rated value, the compressor can’t start.
Result: Compressor hums but won’t start. Repeats every 5 minutes.
Fan Motor Failure
Component: Condenser fan motor
Mechanism: Fan motor bearings wear out from continuous operation. The fan stops spinning, preventing heat rejection from the condenser.
Result: Compressor overheats, thermal overload trips, unit shuts off.
Compressor Seizure
Component: Hermetic compressor
Mechanism: Oil degrades from sustained high temperatures, causing varnish and sludge to form. Bearings seize. Or, refrigerant leaks cause oil to be pumped out of the compressor.
Result: Compressor runs but makes loud humming. No dehumidification. Eventually locks up.
Refrigerant Leak
Component: Sealed system brazed joints
Mechanism: Copper-to-aluminum brazed joints develop micro-cracks from thermal cycling. Refrigerant slowly leaks out.
Result: Low refrigerant = poor cooling = no water collection. Compressor runs but no temperature differential.
Usage Patterns That Cause Compressor Failure
| Pattern | How It Causes Compressor Failure | Severity |
|---|---|---|
| Continuous operation 24/7 | No oil return, sustained high temperatures | 🔴 High |
| Dusty environment | Condenser coils clog, compressor overheats | 🟠 High |
| Frequent power outages | Capacitor stress from repeated restarts | 🟡 Medium |
| Enclosed space | Poor airflow, compressor overheats | 🟠 High |
| Dirty filter | Reduced airflow, coil icing, compressor strain | 🟡 Medium |
Maintenance Traps Sellers Don’t Mention
| Trap | What It Is | Cost of Neglect |
|---|---|---|
| No capacitor replacement | Capacitors degrade over time | Compressor failure: $500-700 |
| Dirty coils | Condenser coils clogged | Compressor overheating: $500-700 |
| Clogged filter | Reduced airflow | Compressor strain: $500-700 |
| Fan not spinning | Fan motor failure | Compressor overheating: $500-700 |
How to Test a GE Compressor (No Tools Required)
Test 1: The Temperature Differential Test
Step 1: Let the unit run for 15 minutes.
Step 2: Place one hand on the air intake and one on the discharge grille.
Step 3: Feel the temperature difference.
| Result | What It Means |
|---|---|
| 15-25°F warmer at discharge | Compressor is working |
| Less than 10°F difference | Compressor weak or low refrigerant |
| No temperature difference | Compressor not working |
| Discharge is cold | Unit is in defrost or icing |
Test 2: The Compressor Sound Test
Step 1: Unplug the unit. Wait 60 seconds.
Step 2: Plug it back in. Immediately listen at the compressor (back/bottom).
Step 3: Listen for the sequence:
| Sound Sequence | What It Means |
|---|---|
| Click → 60Hz hum → smooth run | Compressor starting normally |
| Click → hum 2-5 sec → click stop | Capacitor or relay issue ($10-40 fix) |
| No click → no sound | Dead compressor or control board |
| Loud hum → no start → hot | Compressor seized (REPLACE) |
Test 3: The Start/Stop Pattern Test
Step 1: Listen to the compressor for 10 minutes.
Step 2: Note the pattern.
| Pattern | What It Means |
|---|---|
| Runs continuously, never stops | Normal in high humidity |
| Runs 5-10 min, stops 5-10 min | Normal cycling |
| Hums 2-5 sec, stops, repeats every 5 min | Capacitor or relay failure ($10-40) |
| Runs 30 sec, stops, repeats | Compressor thermal overload (fan issue or low refrigerant) |
| Never starts | Electrical failure or seized compressor |

FAQ: GE Dehumidifier Humming But Not Starting
Why is my GE dehumidifier humming but not starting?
Most likely the start capacitor has failed. The capacitor loses capacitance, and the compressor can’t get enough starting torque. Fix: Replace the start capacitor ($10-25). This is the #1 cause.
Why does my GE dehumidifier click but not start?
A clicking sound without the compressor starting usually means one of two things:
- Start relay is clicking but the capacitor is dead → Replace capacitor ($10-25)
- The compressor is locked up (seized) → Replace unit ($250-400)
The 10-second sound test will tell you which: click + hum = capacitor; click + no hum = seized.
My GE dehumidifier compressor runs but doesn’t cool — what’s wrong?
If the compressor runs but there’s no temperature difference between intake and discharge, you likely have a refrigerant leak. This is a sealed system issue. Repair cost: $350-650. New unit cost: $250-400. Replace the unit. It’s never economical to repair a refrigerant leak on a sub-$400 dehumidifier.
How do I test my GE dehumidifier compressor?
The 10-second sound test: Unplug. Wait 60 seconds. Plug in. Listen:
- Click → smooth hum → Compressor is working
- Click → hum 2-5 sec → click stop → Capacitor issue ($10-25)
- Click → no hum → Relay or seized compressor
- Loud hum, hot → Compressor seized (REPLACE)
Should I repair or replace my GE dehumidifier if the compressor fails?
- Capacitor failure: 🟢 REPAIR — $10-25 fix
- Start relay failure: 🟢 REPAIR — $20-40 fix
- Fan motor failure: 🟢 REPAIR — $50-100 fix
- Compressor seized: 🔴 REPLACE — $500-700 repair vs $250-400 new
- Refrigerant leak: 🔴 REPLACE — $350-650 repair vs $250-400 new
How long do GE dehumidifier compressors last?
- 24/7 continuous use: 1-2 years
- 12 hours/day: 3-4 years
- Seasonal use: 5-7 years
What’s the 60% rule for dehumidifier repair?
If the repair cost is 60% or more of the price of a new unit, replace the unit. If less than 40%, repair it.
Can I replace a GE dehumidifier capacitor myself?
Yes — if you’re comfortable with basic electrical work. Always unplug the unit first. Part cost: $10-25.
What’s the most common GE compressor issue?
Capacitor failure. In our service logs, 65% of “compressor not working” diagnoses are actually capacitor failures. Replace the capacitor first ($10-25).
Final Bottom Line
GE dehumidifier compressor issues are common — but most are misdiagnosed.
The #1 rule: Replace the capacitor before assuming the compressor is dead.
65% of “compressor not working” issues are capacitor failures ($10-25 fix).
