Repair or replace · Hoods
Hood Controls or Lights Dead
Short answer
When only the lights have gone, the lamps are the first suspect. When the fan, the lights and the heat lamps all stay dark, the fault sits in the supply or the controls. Viking Repair Sammamish tests power at the hood before naming a part, and a failed control on a sound canopy is a repair. Call (425) 610-8986.
- Baffle filter — grease collects on the channels and drains to the bottom
- Blower (ventilator) — the only moving part pulling the air
- Backdraft damper — opens under airflow, falls shut when the fan stops
- Metal duct — smooth and straight is best; every elbow costs draw
- Roof or wall cap — where the air finally leaves the house
- Lights and controls — the lamps and the fan and light switches on the canopy
On the bench
-
We measure each dark socket with a test lamp of the type Viking specifies
It tells us whether the bulbs failed or whatever feeds them
So we stop there when a fresh lamp lights.
-
We measure voltage at the hood's supply connection with the breaker on
It tells us whether power is reaching the hood at all
So we trace the circuit back before we open a control.
-
We measure blower and lights on every knob position from one to five
It tells us whether one control has failed or the whole panel
So we price only the part that stopped answering.
Lamps come before controls
On Viking’s 5 Series professional indoor hoods the lights are 120-volt R20 LED lamps; the use and care guide names a Philips 8-watt bulb, 8R20/F90 2700 DIM, that unscrews. Viking suggests an oven mitt in case the glass breaks. With the hood cool and the power off, that swap is yours.
Hoods 18 inches high also carry heat-lamp outlets on their own push switches. Viking ships no bulbs for them and calls for R40, 120-volt, 250-watt infrared lamps, so an empty socket can pass for a dead switch.
Knobs first, then the breaker
The blower and light knobs push in to pop out, then turn from zero, which is off, up to five. Pop each one out and turn it before deciding anything has failed. If fan, lights and heat lamps all stay dark, check the breaker once.
After that the test is at the supply. Viking hoods are hard-wired with two wires and a ground, and the guide wants power locked off at the service panel before anyone services the hood. That part is ours.
Repair or replace: the signs
Repair it when
- Lamps of the specified type bring the lights straight back
- Power reaches the hood but one knob or switch has stopped answering
Replace it when
- The canopy is damaged and would be replaced even with working controls
- The hood is coming out for another reason, so a control repair buys nothing
Verdict Swap the lamps yourself, then let us test the supply and the controls; a dead switch or knob on a sound canopy is a repair, not a reason to buy a hood.
What it costs here
- Diagnosis visit $89
- Hood controls, switches or wiring quoted after the diagnosis
$89 buys the visit and the full diagnosis. Go ahead with the repair and that $89 is taken off its price. The replacement side is not priced on this page: it depends on the unit you choose and who installs it.
Asked about this
Can I fit a different bulb in my Viking hood lights?
Stay with the lamp Viking names. For 5 Series professional indoor hoods the guide calls for a 120-volt R20 8-watt LED and lists no alternative, and the light knob dims it across five steps. If a correct lamp stays dark, Viking Repair Sammamish tests the socket, (425) 610-8986.
My hood fan started with the knob at zero. Is the control failing?
Not necessarily. On Viking's professional hoods a heat sensor may switch the blower on when the canopy gets hot. If it runs on with the cooking surface cold and switched off, the sensor or the control is suspect. Viking Repair Sammamish tests both, (425) 610-8986.
