RV Appliance Repair and Replacement in Placentia, California

RV appliance repair covers refrigerators, roof air conditioners, furnaces, cooktops, microwaves and washer dryer units. We service Dometic, Norcold and Furrion refrigerators along with the common rooftop air and furnace platforms. Repairs run about $350 to $4,500 at $260 per hour. Work is performed in-shop in Yorba Linda, roughly ten minutes from Placentia.

Why is my RV refrigerator not cooling?

Absorption refrigerators from Dometic and Norcold cool by boiling an ammonia solution, which requires heat, level operation and a working ventilation path. Loss of cooling usually means a failed heating element, a blocked flue, poor ventilation, a control board fault, or a cooling unit that has crystallized internally.

The ventilation check comes first because it is cheap and it is frequently the answer. Insect nests in the burner tube, a blocked lower vent and a missing baffle all starve the flue of draft, and the unit then cannot shed heat regardless of how healthy the cooling unit is.

A crystallized or leaking cooling unit is the terminal diagnosis, identifiable by a yellow residue and an ammonia smell at the back of the unit. At that point the choice is a replacement cooling unit or a switch to a Furrion or residential compressor refrigerator, which changes the electrical picture.

Why does my RV air conditioner freeze up or blow warm?

Freezing over is almost always restricted airflow: a clogged return filter, a crushed or disconnected duct, or a blower wheel packed with dust. Blowing warm without freezing points instead at the capacitor, the compressor, the control board or a refrigerant loss that cannot be recharged on a sealed rooftop unit.

The capacitor is the most common single failure. A weak start capacitor lets the fan run while the compressor merely hums and trips on thermal overload, which owners describe as an air conditioner that blows air but never gets cold on a hot afternoon.

Duct sealing matters in ducted coaches. A disconnected plenum inside the ceiling dumps conditioned air into the roof cavity instead of the living space, so the unit runs constantly, the coach never cools, and the evaporator ices from the reduced return.

What causes an RV furnace to run but not produce heat?

A furnace that spins the blower and then shuts down without igniting is usually failing a safety interlock. The sail switch has to prove airflow, the limit switch has to prove the chamber is not overheating, and the igniter and gas valve have to deliver flame within the trial period.

Low battery voltage is an underrated cause. RV furnace blowers need adequate current to spin fast enough to close the sail switch, so a coach on a tired battery bank will crank the blower, fail to prove airflow and lock out, which reads as a furnace fault rather than an electrical one.

Cooktops and ovens fail more simply, at the igniter, the thermocouple or the regulator. Any propane appliance repair here includes a leak test on the affected run, because a leaking fitting inside a cabinet is a hazard that outweighs whatever the original complaint was.

Questions we get asked

Should I repair my Norcold refrigerator or replace it?
If the cooling unit has failed, compare a replacement cooling unit against a new Furrion or compressor refrigerator. Compressor units cool faster, tolerate being off level and are less fussy, but they draw more power, so the decision usually depends on whether your battery and inverter capacity can support one.
How much does RV appliance repair cost?
Most jobs land between $350 and $4,500. A rooftop air conditioner capacitor or a furnace sail switch is near the low end. A replacement cooling unit, a new rooftop air conditioner or a refrigerator swap with supporting electrical work sits at the upper end, including labor at $260 per hour.
Can you install a residential refrigerator in my coach?
Yes, and the electrical review comes with it. A residential unit needs inverter capacity and a battery bank that can carry it overnight, plus framing and securing so it survives road travel. Placentia owners frequently pair the swap with added solar so the bank actually recovers between trips.
My air conditioner ices over every afternoon. Is it low on refrigerant?
Usually not. Rooftop units are sealed systems, and icing is far more often a return air restriction: a dirty filter, a packed blower wheel or a disconnected duct. We check airflow and current draw first, because adding refrigerant to a unit that is actually starved of air fixes nothing.
