ProSun Lamp Holder Replacement: Fix Loose or Dead Lamps

Diagnose a tanning bed lamp that won't light or a loose socket before you buy parts. Learn when a ProSun lamp holder replacement solves the problem.
Quick answer
If a ProSun lamp is dead or flickers only when you wiggle it, the lamp holder is the likely culprit. Replace the holder with the ProSun Lamp Holder (M-13, Part # ELEC3502205) after confirming the lamp itself and the power supply are good.
Why ProSun holders fail before the lamp does
Lamp holders take more wear than most tanning bed parts. Every lamp change flexes the contacts, and heat cycles slowly loosen the grip. A holder that feels loose or shows scorching is a sign the contact has lost tension or arced, even if the lamp still works in another socket.
The ProSun Lamp Holder is a direct replacement for ProSun Tanning Units, so fit is not the issue once you have confirmed the holder is at fault. The harder question is separating a bad holder from a bad lamp or a tripped circuit.
When the problem is not the holder
A lamp that is dark at both ends usually has a broken filament, not a bad socket. Swap it into a holder that you know works before ordering parts. If it stays dark there, replace the lamp, not the holder.
If several lamps across different holders are out at once, stop and check the bed's breaker, timer, and main switch first. A single holder replacement will not fix a power supply problem, and the catalog does not list electrical specifications for the holder, so match it to your ProSun model rather than guessing.
What to check before you order
Confirm your bed is a ProSun Tanning Unit and that the failed holder matches the M-13 plastic holder shape. The catalog lists the part as ELEC3502205 and includes one holder per order, so count how many positions are actually bad before buying.
Unplug the bed and let lamps cool before inspecting. Look for cracked plastic, discolored contacts, or a lamp that rocks in the socket. Those are the visible signs that justify a holder swap.
Diagnose the lamp before you replace the holder
- Symptom: lamp completely dark: Remove the lamp and inspect the filament. If it is broken or the ends are black, replace the lamp. If the filament looks intact, test the lamp in a holder that works. A lamp that works in another holder points to the original holder, not the lamp.
- Symptom: lamp flickers or lights only when wiggled: With the bed unplugged, check the holder contacts for looseness, corrosion, or scorching. A holder that will not grip the lamp firmly needs replacement. Flickering that changes with movement is the clearest sign of a loose tanning lamp socket.
- Symptom: several lamps out at once: Check the breaker, timer, and main power switch before touching any holder. If power is present at the bed but multiple holders are dead, stop and consult a technician. Multiple failures are a power or wiring issue, not a holder issue.
- Corrective action: replace the holder: Unplug the bed, remove the lamp, and swap the failed holder for the ProSun Lamp Holder (M-13, ELEC3502205). Reinstall the lamp and test. If the new holder still does not light the lamp, stop and have the bed serviced. One holder per order; count failed positions before buying.
