Kenmore Elite 58077187710 room air conditioner Parts

To reset your Kenmore Elite room air conditioner model 58077187710, use the reset (current interrupter) on the power cord plug: press TEST, then press RESET. If the RESET button will not stay engaged, stop using the unit and have it serviced.

Reset steps (power cord plug)

• Turn the air conditioner OFF.
• Locate the TEST and RESET buttons on the plug head.
• Press TEST; the RESET button should pop out.
• Press RESET firmly.
• Turn the unit back ON and set COOL mode.

If it still will not start after resetting

These checks solve the most common “won’t start” and “trips breaker” complaints.

• Make sure the plug is fully seated in the outlet.
• Check the home circuit breaker/fuse and reset/replace if needed.
• Avoid extension cords; plug the unit directly into a dedicated outlet.
• If you turned it off and back on quickly, wait 3 minutes (compressor delay) before restarting.
• If airflow is weak, clean the filter; a clogged filter can cause poor cooling and other issues (see 58077187710 owner's manual).

Quick reference: what the buttons mean

Button	What it does	What you should see
TEST	Trips the safety device	RESET pops out (click)
RESET	Restores power through the cord	Button stays in

Why it matters

The TEST/RESET device helps protect against electrical faults. Resetting it correctly restores power safely; if it will not stay engaged, the cord or unit needs attention before continued operation.

For the Kenmore Elite room air conditioner model 58077187710 (18,000 BTU), the Use & Care Guide specifies a standard 240 V, 3-wire grounding receptacle (15 A, 240 VAC, 60 Hz). Confirm the exact electrical rating on the unit’s rating plate and in the 58077187710 use & care guide.

What to plug it into (typical for 18,000 BTU)

Most 18,000 BTU window and room air conditioners are designed for a dedicated 240 V circuit because the compressor and fan motor draw more current than 120 V units.

• Use a standard 240 V, 3-wire grounding receptacle
• Use a dedicated circuit (avoid sharing with other high-draw devices)
• Match the breaker/fuse size to the manual and rating plate
• Do not use an extension cord, surge protector, or multi-outlet adapter
• If the plug has TEST/RESET, keep it in good condition and replace the cord if damaged

Quick voltage comparison by BTU class (from the guide)

Cooling capacity	Typical receptacle	Typical circuit protection
15,000 BTU	120 V grounded	15 A
18,000 BTU (58077187710)	240 V grounded	15 A
25,000 BTU	240 V grounded	20 A

Why it matters

Using the correct voltage and receptacle prevents nuisance breaker trips, protects the electronic control board, and helps the compressor start reliably. Incorrect power (or extension cords) can cause overheating and repeated shutdowns.

If your breaker trips or the unit will not power on

These checks align with common symptoms in the troubleshooting guidance:

• Reset the plug (if equipped) and verify it stays engaged
• Check the home breaker/fuse and reset/replace as needed
• Make sure the unit is on a single, dedicated outlet
• Turn the unit off and wait 3 minutes before restarting (compressor delay)
• If you suspect cord damage, replace the lg room air conditioner power cord EAD63469505

On Kenmore Elite model 58077187710, CH-34 indicates a high-pressure condition in the sealed system; to protect the unit, the control can shut the compressor off until pressures return to a safe range. Use the troubleshooting guidance in the 58077187710 owner's manual.

What usually causes CH-34

A high-pressure fault is typically triggered when the unit cannot reject heat outdoors or airflow is restricted.

• Dirty or blocked condenser coil (outdoor side) reducing heat transfer
• Airflow blocked by a closed vent, curtains, furniture, or a clogged filter
• Outdoor temperature is extremely high and the unit is working at maximum load
• Condenser fan issue (fan not running, damaged blade, or airflow obstruction)
• Sealed-system restriction or overcharge (requires a sealed-system technician)

What we recommend you do first

Start with the simplest airflow and cleaning checks before assuming an electrical control problem.

1. Turn the air conditioner OFF and unplug it for 5 minutes (basic reset).
2. Remove and clean or replace the filter; for this model, check the room air conditioner air filter 5231A20027A.
3. Make sure the rear of the unit has clear airflow outside (no screens packed with lint, leaves, or debris).
4. Clean the condenser coil carefully; avoid bending fins.
5. Restore power and run High Cool for 10 to 15 minutes to see if the code returns.

Quick checks: symptoms and likely direction

What you notice	What it often points to	What to do next
Weak airflow from the front grille	Filter or evaporator airflow restriction	Clean/replace filter; verify louvers are open
Unit runs, then trips to CH-34 on hot afternoons	High load or poor outdoor heat rejection	Improve outdoor airflow; clean condenser
Fan sounds abnormal or airflow outside feels weak	Condenser fan or blade problem	Inspect fan area for obstructions; service if needed
Code returns quickly after cleaning	Sealed-system pressure issue	Schedule sealed-system service

Why it matters

CH-34 is a compressor protection code. Continuing to run with restricted airflow can overheat the compressor, reduce cooling performance, and shorten the life of key components like the electronic control.
