Pulled the relay off of the condenser motor (3 pin connection) and removed 2 wire feeds. Reversed the procedure for the install. Ordered the new relay and decided to replace the run capacitor as well just to be safe. Appliance Parts Pros was a really good website to help identify the 2 part numbers and see pictures that confirmed they were the same as the original. Price was competitive with others. Read more

Microwave High Voltage Capacitor
Genuine Frigidaire part
By: Frigidaire
Part Number: 5304467671

This is a high voltage capacitor used in the microwave's magnetron circuit. It stores and releases electrical energy to help power the magnetron, which generates the microwaves that heat food. Replace this capacitor if the microwave runs but does not heat, hums loudly without cooking, or if the capacitor has visibly bulged or leaked. Always discharge the capacitor before handling, as it can retain a dangerous charge even when unplugged.

Do-It-Yourself Stories from Customers like You Frigidaire professional microwave not heating everything else was working ok eg (turntable and lights) unit had a loud humming sound when it stopped heating   Fran P. • Laurel Springs , NJ • December 15, 2014

Replaced the magnetron and high voltage capacitor. I tried replacing only the diode (rectifier) first with no luck. I hope this is helpful. Read more

Microwave High Voltage Capacitor
Genuine Samsung part
By: Samsung
Part Number: 2501-001011

Microwave stopped heating or makes humming noise before shutting off? The high voltage capacitor often fails first. DIY repair in under 30 minutes.

Do-It-Yourself Stories from Customers like You Microwave blowing fuse for Magnetron / high voltage circuit (humming noise prior to fuse opening).   Keith G. • Houston , TX • April 27, 2020

Main Fuse did not open, only fuse for high voltage section was opened. Prior to the fuse blowing a louder than normal hum was heard from microwave for 1-2 seconds prior. Easy fix is the high voltage capacitor, so first checked the voltage across the capacitor terminals to ensure capacitor was discharged. Typically should be reasonably discharged within 30sec-1min assuming drain resistor is still in place. Removed the high voltage cap, and checked the capacitance and did not get a reading....

Run Capacitor (Refrigerator Compressor)
Genuine Frigidaire part
By: Frigidaire
Part Number: 297286810

This run capacitor helps the refrigerator compressor start and run smoothly, restoring normal operation when a weak or failed capacitor causes the compressor to struggle. Replacing a faulty capacitor can reduce humming and improve cooling performance. What it does:

  • Provides continuous phase-shift to the compressor motor for stable running.
  • Helps maintain proper compressor speed and efficiency during operation.
  • Commonly replaced when the compressor hums, won't stay running, or cooling is inconsistent.
  • Reduces risk of repeated motor cycling caused by a weak or open capacitor.
What's included: One run capacitor. Install notes:
  • Always disconnect power to the appliance before accessing electrical components.
  • Discharge the capacitor before handling; capacitors can hold a charge even when powered off.
  • Observe terminal orientation and mounting location; replace with the same type and ratings.

Part Number: 0CZZJB2010G

Refrigerator won't start or stops running? A failed capacitor disrupts motor circuits. This film radial capacitor restores voltage stability and operation.

Do-It-Yourself Stories from Customers like You Lg refrigerator wound not start   Steve S. • Peoria , AZ • May 28, 2016

For an emergency fix I installed a 3 in1 kit disabling the original start cap and wiring in the original run cap to the run winding. Ordered the proper PTC and overload from Appliance Parts Pros and installed them 2 weeks later. The original start and run capacitor were good, rewired back to design specs. The original PTC had pins 1,2 and 3, the replacement had 2,3 and 4. Only wiring change was to install the red wire from pin 1 on the original PTC to pin 4 on the new PTC. Read more
