DreyooCarrier HVAC Motor Contactor, 24V 30 A Coil 1 Pole Replacement Relays Compatible with C230B, Air Conditioner, Heat Pump, Refrigeration Systems

Perfect fit and function.

Our AC was making an electrical arcing noise when running. I assumed it was the relay and replaced it with this item. It fixed the issue and is working perfectly. When I dismantled the old one I noticed that one of the electrical contact buttons had come lose which was what was causing the arcing.Great value for money and easy to replace. Just make a note of the electrical connections and reconnect.

Was uncertain of quality but upon receiving found it appears to be good quality. Easy install in a few minutes. Should replace periodically since these contactors cycle enormous times during HVAC season. Cheaper than OEM parts but seems to function well with a savings of over 75% over new OEM parts price. Will buy again and re-ordered after receiving my first one to check quality.

fit perfectly, worked very well

Compare with my old OEM 25+ yeas HVAC relay (still working OK, connectors a little worn out). New relay coil has 17 Ohms resistance and when it energized it draws 0.25 Amps and makes buzzing sound (I do not know if it is normal for AC voltage). Old one has a bigger coil 8 Ohms resistance, draws 0.5 Amps and it is quiet. Mount is the same, still working (one week), it is inexpensive just have one sparer.Notes, most thermostats can handle up to 1 Amps load.

Thank you!

I used it on my A/C unit, and it worked right away- after I connected it of course!

Imagine my horror when returning from work late on a July evening and finding my home AC blowing nonstop hot air again (like my ex-wife). I've kept this thing limping along for years (my AC unit, not my ex-wife), Frankensteining the system to the near reaches of the Ship of Theseus paradox... but alas, a new symptom to Google. Troubleshooting suggested it may be the contactor. If it were a more expensive part, I would have thought twice before ordering a replacement without confirmation. But at this price? Buy it, ship it, no second thoughts. It was home the next morning before 8am.I had it installed in no time and was only moderately late for work. Easy drop-in replacement for a Siemens Catalog # 45EG10AJA690R / CONT1P030024V. Shut off the breaker, exchange the clips 1 by 1, screw in the mains, bolt to the unit, re-electrify the breaker. Done & done. Biggest pain was the mosquito bites on my ankles.Got home tonight thrilled to find the unit has been blowing cold and cycling perfectly all day. From surprise breakdown to complete fixed again in ~12 hours.
