Dmitry visited today and helped fixing GE oven. He was quick to diagnose issue and fixed it at reasonable price.
I haven't met a man as professional and honest as Alex in a long time. He really does the best in the interest of the customer.
Igor from Boost Appliance Service repaired my subzero refrigerator. He needed to order parts but in general the repair turned over was fast and my fridge is working perfectly right now. The best service in Morristown. Highly recommend!
I was very impressed with their great availability. They scheduled me in quickly and Ramiz was very knowledgeable and detail oriented. The error code we had was not appearing but he still spent 45 minutes making sure everything was checked. I appreciated his attention to detail and not just leaving when the error code wasn't there. We will definitely be returning customers!
A+++ Service. Boost Appliance Service is great. I called on Monday and Mr. Igor came the next day to repair the defrost sensor and drain line of my fridge, he also did thorough maintenance checks on my laundry dryer and laundry washer machine. 3 appliances all in one day. Highly recommended. Answered all my questions and showed me how to maintain my appliances. Thank you.
Eddie did an EXCELLENT job diagnosing, repairing and cleaning my washer and dryer. Completely disassembled it, made it run smoother than ever and made the inside shine like new.
Bergen County water tests hard in Closter — typically 8 to 11 grains per gallon depending on the block — and that mineral load destroys fill valves faster than most homeowners expect. The Tudors and custom colonials off Schraalenburgh Road tend to run Sub-Zero or Thermador refrigerators, and both brands respond poorly to scale buildup in the water inlet assembly. Closter is a small borough; we're typically on-site within 2 hours of your call. Reach us at (201) 555-0199.
Most of 07624 was built between the 1950s and 1980s — good construction, but plumbing that wasn't designed around the clearance tolerances of modern panel-ready Sub-Zero or Bosch column units. The streets off Harrington Avenue and closer to the Alpine border have seen heavy kitchen gut-renovations with built-in refrigerators dropped into tight cabinet cutouts. Reaching the module assembly without damaging custom cabinetry takes the right tools — not just a standard service call approach. Homes near Closter Nature Center and along Piermont Road tend to run older copper supply lines — quarter-inch tubing that's been in place since the original build. That tubing narrows over time from calcium deposits, and by the time cube production slows noticeably, the restriction is usually severe. Several houses near the Closter Plaza area have panel-ready Bosch or Sub-Zero column units installed flush behind cabinetry panels during recent renovations. Pulling those for service without scratching the custom millwork is a different operation than a freestanding call. The borough's position near the Palisades puts homes on the western ridge — up toward County Road — in a microclimate that runs 3 to 5 degrees colder in winter. Exterior-wall refrigerator installations up there are more likely to freeze the supply line than the same setup would in a central-Closter home.
Common Ice Maker Issues in Closter
Mineral Scale Blocking the Water Inlet Valve
Calcium deposits from northern Bergen County's hard water accumulate inside the solenoid-controlled water inlet valve — the part that meters water into the ice mold on each cycle. Sub-Zero units with the module mounted at the top of the fresh food section are especially prone to slow buildup. Production drops off gradually, then stops entirely. Sometimes the unit cycles without dropping cubes — that's the valve restricting flow before it fails completely. Descaling or swapping the valve usually wraps up on the first visit.
Frozen Supply Line Along Exterior Cabinet Walls
The quarter-inch copper or braided supply line running behind the refrigerator can freeze where it passes near an outside-facing wall panel. Thermador column refrigerators installed against exterior walls in Closter's older builds show this pattern most winters. The freeze point is almost always within 6 inches of an uninsulated stud cavity. Reinsulating the line and nudging the freezer thermostat up half a degree usually prevents it from recurring.
Optical Sensor Failure Producing Small or Misshapen Cubes
KitchenAid and Bosch built-in units with optical ice level sensors sometimes misread the bin as full when it isn't, cutting the freeze cycle short. The cubes that do drop come out undersized or hollow — a clear symptom. On Bosch units, error code E15 sometimes accompanies this alongside the undersized cube pattern. Diagnosis means ruling out a stuck ejector arm first, then replacing the sensor module or reflashing the control board if needed.
Drive Motor Wear in Older Sub-Zero Modules
Sub-Zero refrigerators from the late 1990s through early 2010s — common in Closter's renovated colonials and expanded ranch homes — use a standalone module that sits above the fresh food compartment. The drive motor and ejector wheel wear out independently of the refrigeration system. Symptoms: the arm cycles but no cubes drop, or the unit makes a grinding noise every 90 minutes on the dot. That rhythm is the harvest cycle timing out. Module replacement is a flat repair, and we carry Sub-Zero assemblies in the van.
Frequently Asked Questions
How fast can you get to Closter for ice maker repair?▼
Most calls in 07624 get same-day service — usually within 2 hours. Parking is easy at most Closter addresses; driveways are standard, and street parking near the downtown blocks is generally open. Evening slots available weekdays. Call (201) 555-0199 or schedule online.
Do you repair Sub-Zero and Thermador units?▼
Yes — Sub-Zero module replacements and Thermador fill valve swaps are two of the more common jobs we handle in Bergen County. KitchenAid and Bosch built-in units with sensor or control board faults are also routine. Parts for all four brands travel in the van. For older Sub-Zero refrigerators, we carry the full module assembly, not just the solenoid.
What does a typical repair cost in Closter?▼
Diagnostic fee applies toward the repair if you proceed. Fill valve and sensor replacements generally run $150–$280 in parts and labor combined. Sub-Zero module swaps sit at the higher end — typically $280–$420 depending on the unit generation. Same-day resolution is the norm when the diagnosis is clean. Call (201) 555-0199 to confirm availability before booking.
