What are error codes anyway?
Error codes help people know when their air conditioning system needs to be repaired or isn’t working optimally. Each error code has a meaning to help you understand the problem and what needs to be done to fix it.
Below are the error codes for Carrier systems and the matching explanation.
If an E1 error code shows up in your air handler, that means there is a communication error either with the indoor unit or the outdoor unit. The causes for this could be a wiring mistake, or a faulty control board with the indoor unit or the outdoor unit.

Problem solve ho gay👍👌

[@SAHNIAIRCONDITION]

Very good sir g

[@ravjohn2]

Can you explain in english what you repaired to solve this error E1?

[@ravjohn2]

My Carrier worked fine for 4 years and now it shows error E1

[@azkhan8407]

He just changed the connection wire of outdoor unit

[@Manjeetelectronitips]

Out dor khol k dekho fan ek hi hota h

[@purnimaservices4431]

😄😄😄😄😂thik bola Alag se fan nahi hota

[@diljeetsingh389]

NF ka matalab kiya hai sir

[@devmalakar2412]

Wire change karne ke bad bhi nahin chal raha hai auto aur

[@seemantgupta8748]

kitna kharcha hota h isme?

[@Kachoora]

Mera 5000 ka kharcha ho gaya 😅

[@seetalparmar3510]

1ooo

[@nileshsonar9]

​@@Kachoorakya problem tha

[@nikhilkale1840]

Maine to bhangar me dal diya ac 8000 ka kharcha aya, PCB ka issue tha outdoor unit me
