Common problems on the Kenmore Elite 79578773801 bottom-mount refrigerator are weak or uneven cooling, frost buildup, water leaks, ice maker or dispenser issues, and unusual fan noise. Most of these trace back to airflow restrictions, dirty condenser coils, door sealing problems, or a defrost or water-supply component that needs service (see the owner's manual).

Most common symptoms and what usually causes them

• Refrigerator or freezer too warm: blocked air vents, frequent door openings, controls not set for conditions, or dirty condenser coils
• Frost or ice crystals on frozen food: door not closing fully or door opened often
• Interior moisture buildup: humid conditions, frequent door openings, or doors not sealing
• Water leaking or puddles: clogged/iced drain path, loose water line connection, or a valve/tubing issue
• Noisy operation: evaporator fan area icing, failing fan motor, or debris near the condenser fan

Quick checks we recommend first (no parts required)

1. Confirm airflow: make sure packages are not blocking vents between freezer and fresh-food sections.
2. Adjust temperatures correctly: change the refrigerator setting first, then wait 24 hours before judging results; adjust the freezer after that if needed.
3. Clean condenser coils: dusty coils commonly cause poor cooling and longer run times.
4. Check door closing and gaskets: clean the gasket and the surface it touches; if it sticks, apply a thin coat of paraffin wax after cleaning.
5. After a power interruption: allow temperatures to stabilize and re-check settings.

On a Kenmore Elite 79578773801 bottom-mount refrigerator, dH (often shown as Er dH) points to a defrost heating problem. The refrigerator is not sensing normal defrost heater operation, so frost can build up on the evaporator and reduce cooling. Use the owner's manual for model-specific troubleshooting and safety steps.

What you’ll usually notice

• Refrigerator section warming up while the freezer seems “okay” at first
• Frost or ice buildup behind the rear freezer panel
• Fan noise changes (fan hitting ice) or reduced airflow
• Longer run times and temperature swings
• Water leaking or refreezing from a clogged defrost drain

Quick checks we recommend (safe, practical steps)

1. Power reset: Unplug the refrigerator for 5 minutes, then restore power and watch for the code returning.
2. Airflow check: Make sure vents are not blocked by food packages.
3. Look for heavy frost: If the rear freezer panel is packed with frost, the defrost system is the likely cause.
4. Inspect the drain area: Ice around the drain trough can happen when defrost isn’t working consistently.
5. If you open panels: Unplug power first; sharp metal edges are common.

Parts commonly involved in a dH/defrost heat issue

If diagnosis confirms a defrost failure, these parts are frequent suspects on bottom-mount designs:

What it does	Part that often fails	Example part for this model
Measures coil temperature during defrost	Defrost sensor/thermistor	Refrigerator defrost sensor assembly 6615JB2005H
Melts frost off the evaporator	Defrost heater	Lg refrigerator defrost heater 5300JK1005D
Moves air across the evaporator	Evaporator fan motor/blade	Refrigerator evaporator fan motor 4681JB1027C / refrigerator evaporator fan blade 5901JA1021A

Why it matters

When the defrost heater circuit is not working, frost builds up on the evaporator coil and blocks airflow. That forces the compressor and fans to run longer, which can lead to poor cooling performance and food spoilage.

Water leaking from the bottom of your Kenmore 79578773801 bottom-mount refrigerator is usually caused by a clogged defrost drain overflowing into the base, or a leak in the water supply connections/tubing for the dispenser or ice maker. Start by checking for ice or debris in the drain path and for drips at the rear water valve and tubing fittings; see the owner's manual for access and safety steps.

Quick checks (most common causes)

• Clogged defrost drain: Meltwater can back up, run under the freezer, and spill into the bottom pan or onto the floor.
• Leaking water line connection: The manual calls out checking for drips at tubing connections and tightening any that leak.
• Cracked or loose water tubing: A pinhole or rubbed-through line can drip and track to the front.
• Water inlet valve seepage: A valve can weep slowly even when not dispensing.
• Drain tube issue: A split or misrouted drain tube can dump water into the machine compartment.

Step-by-step: isolate where the water is coming from

1. Confirm it is water, not defrost melt: If it happens after door openings or during humid weather, suspect the defrost drain.
2. Pull the refrigerator out and inspect the back:
   • Look for wetness around the valve area and tubing.
   • Check the floor behind the unit for a trail that points to the source.
3. Check the water line fittings for drips (with the water on):
   • Tighten any connection that leaks.
   • Make sure the tubing is fully seated in the fitting.
4. Inspect the drain system:
   • Look for ice buildup in the freezer floor or under the evaporator cover.
   • Clear the drain opening with hot water (turkey baster works well) and remove debris.

Parts that commonly fix bottom leaks

Symptom you see	Likely area	Part to consider
Water pooling under freezer drawer	Defrost drain path	Refrigerator drain tube 5251JA3003D
Drips at rear valve or slow seep	Water valve	Refrigerator water inlet valve MJX41178908
Wet tubing or pinhole spray	Water line	Refrigerator water tubing MJU62070602

Why it matters

A small leak can turn into floor damage, ice buildup in the freezer, and poor cooling if airflow gets blocked. Fixing the source early also helps prevent repeated puddles and moldy odors.

A Kenmore Elite 79578773801 bottom-mount refrigerator typically lasts 10 to 15 years. Regular maintenance (especially cleaning condenser coils and keeping door gaskets sealing) helps you reach the upper end of that range and reduces the chance of expensive cooling-system repairs.

Typical lifespan and what affects it

Most refrigerators in this class land in the 10 to 15 year window. The biggest factors that move lifespan up or down are:

• Condenser coil cleanliness (dust buildup makes the compressor run hotter and longer)
• Door gasket condition (air leaks cause longer run times and frost issues)
• Room temperature and ventilation (hot kitchens and tight clearances increase run time)
• How often doors are opened and how full the compartments are
• Water and ice system upkeep (filters, valves, tubing, and leak prevention)

Maintenance that adds years (high impact)

We recommend these habits for the 795.7877 series bottom freezer design:

• Clean the condenser coils on a regular schedule (more often with pets)
• Inspect and wipe the door liner and gaskets so they seal without gaps
• Keep vents inside the refrigerator and freezer unblocked for proper air circulation
• Replace water filtration on schedule and flush air from the water line after service
• Address unusual noises early (fan motors and blades are common wear items)

Quick guide: symptoms vs. what they usually mean

Symptom	Common cause	What to check first
Runs most of the time	Dirty coils, warm room, frequent door openings	Coil cleaning and door sealing
Frost buildup or warm temps	Air leak, airflow restriction, defrost issue	Gaskets, vents, defrost components
Water under fridge	Drain restriction or tubing leak	Drain path and water tubing
No ice or slow water	Filter restriction or inlet valve issue	Filter, then inlet valve

Why it matters

Longer run times are normal in modern refrigerators, but chronic overworking shortens component life. Keeping airflow and heat transfer in good shape helps the compressor and fans operate in a normal duty cycle, which is key to reaching a full service life.

For model-specific care and cleaning intervals, follow the owner's manual.
